### 1 – Texas Instruments TI-36X Pro Engineering/Scientific Calculator

Product description\n\nA sophisticated four-line science calculator with advanced math and science features, ideal for graphics-free computer science and engineering courses. Amazon.com\n\nIdeal for students of all levels â€” from high school algebra to college math analysis â€” Texas TI36 equipments combine many strokes into one compact and affordable unit. This solar calculator combines statistical analysis, logical operations, and unit conversion functions in a single scan package.\n\nMathematics students will appreciate the TI36X\’s ability to perform trigonometric equations and calculate angular units (radios, degrees, and degrees) when performing trigonometric functions. Everyone will find a metric conversion calculator useful.\n\nThe TI36X\’s single line LCD is a bit tricky to read when the device is on a desk, and users looking for graphical features will have to look elsewhere. Overall, however, for a calculator in this price range, the TI36X provides enough power for most high-level math and science problems. Top Reviews I am an engineering student. This is the third calculator that I purchased in the past year, after the TI-30 and the TI-89, both of which still work.That does not include a calculator app that I purchased which I actually use most of all. I bought this one because often professors will limit the model of calculators allowed on his/her test to the ones that can be used on the PE and FE exams, making this one allowable unlike my TI-89. I’m not going to compare this to the TI-89 because they are in different categories. This calculator is better than the TI-30 due to its capabilities of performing integrals and derivatives, but the number one reason I bought this to replace my 30 was that it could perform row reduced echelon form (rref) on small matrices. Don’t know what that is? Suppose you have three equations and three unknown variables, rref can solve those variables for you. This can be useful in Statics class or for those taking algebra. For those of you taking linear algebra I think you are going to use something more powerful because the Ti-36X Pro limits matrix size and you are likely to perform other operations that this calculator cannot handle. I’m not going to get into all the features that the 36 has that the 30 does not, but I will mention that I like that the 36 uses E for inputting scientific notation compared to the 30’s x10^n. It takes up less space on the screen and looks cleaner.The physical construction of the calculators are near identical. I find that the TI-36 has more snappy keys, which I prefer, because it better informs me when I have pressed the key and is better at preventing the accidental pressing of other keys. I also like the black color significantly more. Makes it look more sleek and business minded than the color that makes the 30 look like a toy.After having said all that, there is one CON to this calculator in my experience. The silver keys. The coating and texturing is kind of odd in the way they reflect light. Sure they look cool but it is also more difficult to read these keys. I cannot tell you how many times I have accidentally pressed the plus sign instead of the multiplication. Sure, during those times I was in more of a hurry and a bit on the careless side, but the design of a calculator needs to take that into consideration. It would be better if these keys were just black with white symbols instead of attempting to look fancy. Perhaps more use of this calculator will resolve that, but I don’t have this problem with the 30, which places the operation keys in the same locations. Now with that in mind, I still decide to use the 36 instead of the 30 during my tests, even though I wasn’t going to be using the integral, derivative and rref functions. . The best non-programmable TI calculator there is, this is the most powerful scientific calculator allowed on the FE/PE engineering exams. It has some of the familiar button placements that will help transition from the more powerful models, but retains many of the same powerful functions. It even has functions not available on the TI-84 Plus CE:A. You can solve systems of equations with 2 to 3 variables without appropriating matrix functions for the chore. You can solve quadratic equations as well.B. Suppose you need to evaluate a function many times. You can either enter a formula with the appropriate variable and evaluate it at a certain value, or use “table” to list the values at an interval of your choice, say starting x at 0 and step by 0.2. I do have some gripes:1. The arithmetic buttons are placed one row higher than on the graphic calculators, This takes time to adjust.2. After deleting a previous calculation, the “answer” remains, so you may be looking at a previous result but “ans” may carry a different value.3. Some functions, such as with vectors, are cumbersome to produce.4. To convert fractions and radicals into decimals, you need to use the “base n” menu, not the “convert” menu.5. Most importantly, the protective cover is hard to get in and out of. It’s a poorer design than that for the graphing calculator. . Check out the customer images. The main function keys (far right column) are very hard to read. They are not painted black as shown in the ad. They are only a slight indentation on an otherwise bright silver pad. Unless you have 20/20 vision, or better, you will be probably constantly confuse the ( – ) for the divide sign, and the (+) sign with the times sign. It is only issue that I have with this product, but it’s a big one. Otherwise, it seems to function well. I know that it’s a $20 calculator. But, they all are – or less. I would happily have paid $30 or more for a calculator with function keys that I can easily see. But, this is for school, so I had to keep it simple and non-programable. And, if you’re in direct light it can be even worse as the light reflects easily off the silver paint, so you need to hold it a little sideways to avoid reflection. Not a smart color scheme. . As many other reviewers have said, the silver reflective keys are the one big negative with this otherwise awesome calculator. Idea #1 – I did what others suggested and used a fine point sharpie to color in the button etchings. Slightly better, but the reflective paint still made the buttons hard to see.Idea #2 – Turns out the Texas Instruments TI-30XS [https://www.amazon.com/gp/product/B000PDFQ6K] has the exact same keys as the TI-36 Pro. I swapped my TI-36X keys for the TI-30 keys, and my photo shows the before & after result — completely legible keys! It’s been so much nicer with this mod. Swapped the Arrow keys, 2nd, Vars keys too, since it looked better.Yes, this means I had to purchase 2 calculators (hey I waited until they were on sale, don’t judge me). And I had to completely disassemble both calculators. And I had to dremel the circuit boards out to get at the keys. But it worked! The result was totally worth it. NO REGERTS(wait could this mean TI is trying to get us to purchase twice as many calculators?? Well played, TI.) Read more

If you are preparing to take the Official GED Test, this is the calculator youneed to learn on. Every TI Calculator model has keys arranged a bit differently.You need to learn to use this one. TI-30XS MultiView Scientific CalculatorWhen you take the GED test they will have an on screen calculator exactly likethis, however using an on screen calculator is very awkward. For part 2of the math test, they will allow you to use your own calculator but only if itis this exact model. Why they replaced the (CASIO fx-260) with this one, I’ll never understand,but they did. If it works, fix it, right? Why they think they need multi-view etc, I’llnever understand but the calculator for the GED test is now TI-30XS MultiView Scientific CalculatorThis is the only calculator you should use to prepare and have with you for the official GED test. . These are THE BEST calculator to buy for a medium level (middle school through algebra) math student. I teach secondary and post secondary students and this is the calculator I tell them all to buy.It is better than the TI-30XSII because you can see what you had previously input. That is really the main difference between the two calculators and this one allows you to see what you put in before. It’s superior in my opinion. . This is my second time purchasing this calculator, only because I canâ€™t find my old TI-30XS. The last one I had lasted my brother and I at least 7-8 years until I lost it recently! Iâ€™ve seen a few reviews saying that this calculator is awful for math or chemistry and that it doesnâ€™t solve things properly, but that is NOT TRUE AT ALL. Iâ€™ve used this from middle school math all the way to calculus and now college chemistry, and it works great! You just have to be aware of how you put things into the calculator, meaning parentheses are your friends!!! And you get a lot of awareness from that, this calculator is great for students! . You get what you pay for with this calculator. The biggest positive is that the screen allows for fractions, the data and stat function were indispensable and got me through my statistics class. Yayy!! The negative: sometimes this calculator just gives the most random and INCORRECT answers. You always have to verify that the given answer looks correct and if you have time, sometimes you have to repeat to double check. At times, it can make you feel like you are losing your mind and wonder if you really did that bad of a job plugging in the values. I know that others in the class with this type of calculator had similar problems. Just beware. In the end, it can get you through a stats class, but you may also lose valuable points from miscalculations. Also, the memory feature may as well not be there at all: one has to go through so many steps to employ it that it’s sometimes faster to repeat the process. Read more

### 3 – Texas Instruments TI-30XIIS Scientific Calculator, Red

Color: red | Style: 1 pack\n\nA basic two-line calculator combines high school math and science statistics with modern science writing. Top Reviews Do you ever have problems with people recognizing that you’re female? Do people ever have the gall say that you’re a “reasonable” and “practical” person? Finally, are you tired of people mooching off you by asking to use your calculator? If this has happened to you or someone you love, buy this calculator in this obnoxious pink color immediately!No one will be able to mistake you for anything but the pink-loving, somewhat basic girl that you are, and best of all, many, due to their masculinity complexes, will not want to use your calculator merely because of the bright color!But in all seriousness, I bought this because someone stole my factory-color blue version. I bought this to be a little more distinctive so that maybe it won’t happen again.As for the product, package came fast, all buttons work sharply — good feedback when pressed. I personally love this calculator — I can’t stand a casio. TI all the way. I can actually see what I’m taking the logarithm of instead of getting an error once I hit the log button. I would buy this a thousand times over (if I weren’t already broke of course)Enjoy! . As a chemist I use a programmable graphing calculator. However I also tutor high school and college students and have used TI 30 series calculators for that purpose for decades. This calculator is more than adequate for junior high school, high school and most college courses. In addition it is a bargin. Most standardized tests and teachers who allow calculators for tests allow the TI 30 series. It handles calculations found in all high school courses. It comes with a rudimentary instruction sheet and a quick reference card. TI used to package a comprehensive paperback book with this series. That manual is still available online in pdf format as a free download.The package includes the calculator. It has an internal battery that can be replaced with some difficulty. Routinely the calculator relies on a solar cell which operates the device and charges the battery. Classroom light is sufficient to power the solar cell. There is a hard case that slides on to protect the face of the calculator. When not in use the cover can slide on the back for storage. There is a slot in the case to hold the quick reference card. There is also a basic information sheet in the package.For those who worry about such things this is built in the Philippines. The TI 30 series has been one of the most popular entry level scientific calculators since the 1970s. . I purchased this TI for my Business Calculus class. We are required to have a scientific calculator that does not have graphic ability. What I have found about this calculator is that while it works well, there are some additional steps that have to

be taken when doing complex calculations. Where on some calculators you don’t have bracket issues, this one, you have to really think out the steps otherwise the answer will come out incorrect. It does however serve its purpose. Once I figured out the bracket issues, it’s worked like a champ. I would recommend this calculator for those who need one for a math class, but I would invest in another version of the TI scientific calculator for more complex math class. . Our college CE department force all students to buy this type of calculator. It is not bad, but the reflection between two keys are too long. Thus, we can’t type the data quickly. It could be the good claculator for exam of middle school or lower. Not recommment for high school and above. I don’t know why my major department’s professors is so stupid to do that. Read more

### 4 – Texas Instruments TI-30XIIS Scientific Calculator, Black with Blue Accents

The line display shows both records and mathematical results on a single screen for calculating data and scientific functions that have different parts and conversion functions. 1 and 2 overviews of variables statistics of previous records. SAT, ACT and AP Tests Color: Blue Features\n\nThe Texas Instruments TI-30X IIS 2-Line Scientific Calculator has a two-line display and other advanced features that users can use with the TI-30X IIS. The screen displays the equation you are drawing on the top line, and the number or symbol you are currently entering on the second line. After solving the equation, the results will be displayed on the second line and you can use the four arrow keys on the front of the calculator to edit the real equation in any way you like. Û” Ideally, pressing the up arrow multiple times will help you browse through the archives of many previous calculations, which means you can go back to see the answer to the problem. The device uses solar power whenever possible, but can rely on internal batteries (including) if there is not enough light. There are three angles (degrees, radii, and degrees), scientific and engineering notation methods, and even one or two variables in the statistics method. Five variables can also be set in their memory slots. The calculator comes with a back cover. Key Features: Characteristics of two-line display section functions â€¢ Conversion â€¢ Basic scientific and chronometric functions â€¢ Cut and paste records â€¢ Solar and battery powered â€¢ Statistics with one or two variables Ideal: â€¢ General mathematics â€¢ Prealgebra, Ge algebra 1 and 2; Engineering; Statistics; General Sciences Top Reviews This is a fine calculator. It works great. Has more functions than I’ll probably ever use. Then why do I not recommend it?There is a design flaw.I have attached 3 photos where you see the screen. You’ll notice that when you turn the calculator on and look at it from an angle (as you would if you kept it on a desk while you were testing) the numbers are not legible. Your line of sight has to be almost perpendicular or direct to see it clearly. This does not affect the function of the calculator but it gets inconvenient when you have to hover over the calculator or lift it up to read it. In a test taking setting this constant movement was suspicious enough to warrant a warning from the proctor. . I bought this calculator for a chemistry course that didn’t allow graphing calculators. I was hesitant to switch from my TI-89, which I love, and I will say this calculator took some getting used to. The buttons do not seem to be as sensitive as those on the TI-89, and I found that for the first several months I was constantly making “typos” that were actually just the calculator failing to register buttons that I had pressed. The buttons are 100% accurate as long as you type carefully, hitting the keys individually and pressing directly down on them rather than at an angle. So the calculator still works fine. I’m just used to the ease of typing of the other calculators I have used frequently, a TI-84 and a TI-89, which are much more forgiving and can be typed on much faster and more accurately. And obviously, even one missed key can create a big problem when doing a math problem. However, that’s the only reason I’m deducting a start from this review.I’m quite pleased with everything else about this calculator. It has more functions than I expected for such a small device, and I LOVE the fact that it is solar powered (a feature that I wasn’t aware of until I had owned the calculator for several weeks, as they don’t advertise this fact nearly as much as they could). It is slim, light, and sturdy, and I’ve been using it for months with no technical problems. Overall, once I got used to it, I’m satisfied with it. . normal use of a calculator allows for it to sit on the desk and still be able to see what you are entering. the new design of the TI calculator does not. i did not have this issue with my previous TI calculator. so unless you want to hoover over your calculator or pick it up every-time you want to use it so you are looking at it straight on look elsewhere. . Excellent calculator, I use it for university level algebra, trig and chemistry and it has so far held up to the constant workout and being carried around in my book bag and occasionally dropped. This is the version of calculator that my university’s Math Department allows for test taking. “higher” level calculators that graph are not allowed. Read more

### 5 – Casio FX115ESPLUS Scientific Calculator

Modern scientific calculators use natural textbook display technology to display your math experience exactly as it appears in textbooks. A safety pouch prevents damage to the calculator while traveling. The calculator is solar powered and has a backup battery. The calculator is designed for students to select triangle, trigonometry, statistics, first and second algebra, arithmetic, geometry, physics, and more. Top Reviews The four calculators are:1. The TI-36X Pro (scientific calculator)2. The Casio fx-115ES Plus (scientific calculator)3. The Casio fx-991EX ClassWiz (scientific calculator)4. The Casio fx-9750gii (graphing calculator)The problem used for test:B = 1.3271244e+20C = 6.957e+08D = 1.495978707e+11Evaluate:âˆ« (C, 0.999999D) 1 / âˆš(2B(1/x âˆ’ 1/D)) dxThis integral returns the amount of time, in seconds, for an object to fall to the sun’s photosphere (one solar radius = C) starting from a distance of 1 astronomical unit (D), assuming that the sun and the object are initially at rest with respect to each other and are acted upon by no forces other than their mutual gravitational attractio

The TI-36X Pro costs anywhere from $19 to $30 on Amazon.The Casio fx-991EX ClassWiz is the official (and substantial) Casio upgrade to the earlier Casio fx-115ES Plus. For moderately complicated numerical integration chores, the Casio fx-991EX is more than four times faster than its predecessor model. Furthermore, the Casio fx-991EX is more than five times faster than its ostensible competitor from Texas Instruments, the TI-36X Pro. The Casio fx-991EX sells at prices ranging from $14 to $36 on Amazon.But the Casio fx-9750gii is more than three times faster than the Casio fx-991EX ClassWiz and is about 18 times faster than the TI-36X Pro. Reasonable prices on Amazon go from $30 to $37, but there are some sellers (that should be ignored) who are trying to gouge for more.I have solved the indefinite integral analytically. Omitting the intermediate steps,âˆ« 1 / âˆš(2B(1/x âˆ’ 1/D)) dx= âˆš[D/(2B)] { âˆš(XDâˆ’XÂ²) + D arctan[âˆš(D/Xâˆ’1)] }When I used the calculators to solve the integral numerically, I had to avoid entering D itself for X, since that would cause an overflow error. When I use the upper limit of 0.999999D instead, the answer is 5577993.302993855, so all of the calculators’ answers have relative errors of about âˆ’0.001272. . Absolutely wonderful calculator. I originally ordered this calculator as a backup to my TI-36x Pro for the California PE Survey exam, and ended up using this solely because of the degree/minute/second (Â°'”) button. Instead of having to scroll to a menu to find the degree symbol, then minute symbol or second symbol, like in the TI-36x pro, it’s all incorporated into that one button and it also converts to decimal degrees if you’d like. Here’s an example:Convert 5Â°17’36” to decimals.On the TI-36x Pro: Enter 5 -> MATH -> DMS -> 1, 17 -> MATH -> DMS -> 2, 36 -> MATH -> DMS -> 3. Calculator spits out the answer = 5.29.On the Casio Fx-115 ES PLUS: 5 -> Â°'”, 17 -> Â°'” , 36 -> Â°'”, then press Â°'” one more time. Answer = 5.29.That Â°'” button saves so much time!Besides my rant about this little button, the calculator performs all the calculations very quickly, and is pretty fast at solving iterative formulas once you learn how to do it in the manual. The only caveat of this calculator are that it’s a bit too lightweight. When you start punching the numbers quickly, the calculator starts sliding. I often have to hold the calculator in my hand to ensure I’m entering the numbers correctly. The buttons are also a bit flimsy but its more of an aesthetic than functional issue. Still, you can’t go wrong with this calculator! Highly recommended. . So glad I purchased this! I was using a TI previously but found out I was getting 1 in 10 questions wrong on my exams because the keys weren’t always registering the number in the calculation. These buttons have been reliable and I’ve been able to work fast without any errors. They do all the functions I needed for trigonometry and chemistry. I had classmates borrowing my calculator at times because they realized how reliable mine was and how easy the buttons were to understand and use. If I needed to supply one calculator to a college student, this would be the one I’d pick. Now if they need to take calculus, you’ll probably want to look for a graphing calculator, but until then, this is all a student needs! . I feel like Casio should be paying me for the amount of talking I do about this calculator. First off, I’ve owned the fx-115ES for about 2 years now and love it. I love it so much that I’ve not only recommended it to almost anyone who will listen to me, but bought it for two of my friends for their birthdays. When I found out there was a PLUS version of this calculator I was more excited than any one person should be about a calculator, and I didn’t even know what the plus stood for. Turns out it’s a bunch of small things that us math majors really appreciate; lines over repeating decimals, gcd and lcm, remainders (for modular arithmetic), and a bit more memory than its predecessor. BUT IT’S PREDECESSOR WAS ALREADY AMAZING, so basically this calculator is amazing plus.For you calculus students out there that need a scientific calculator for exams: this calculator solves systems of linear equations (with up to 3 variables), quadratics, cubics, does matrix inversion, addition/subtraction and multiplication, gives exact answers (sin(pi/4)=sqrt(2)/2), and is just in general a super easy calculator to use. I’ve been pimping Casio out for a while now, but seriously, for $15 this is the BEST investment you can make in your math education.UPDATE 11/12/2017This calculator still works like a dream and beats everything on the market. As a math instructor I’ve seen probably every scientific calculator out there- certainly all of the TI’s- and not one of them even comes close. One of the most important features I didn’t mention in my original review was its ability to evaluate definite integrals and also derivatives at a point! That’s a crazy feature for a scientific calculator!! I feel just as passionate today about this calculator as I did 5 years ago- do yourself a favor and buy it! Read more

### 6 – Texas Instruments TI-34 MultiView Scientific Calculator

Color: blue, white | Style: 1 pack\n\nAn advanced four-line science calculator for math and science in high and high schools.\r\n\r\n Key features: Four-line display Statistical display with one or two variables for mathematics; Outstanding advanced fractional crushing capabilities Step-by-step component simplification Editing changes, cutting and pasting records using solar and battery power\r\n Ideal for: Preparatory Course in Mathematics, Pre-Algebra, Algebra 1 and General Engineering 2 Top Reviews The calculator seems to be an exact match (except for color) of the ones used in my son’s 8th grade math classes. It’s the same calculator the teacher lends out. Works great. After six months of hauling it around & middle school use, my son came home to share he couldn’t turn it on. Any combination of chaos at school could have traumatized it, but I called TI’s customer service who helped me reset it. They suggested the reset button on the back be pushed with a paperclip to clear the memory & restart it. Worked fabulously and like new again, ready for another daily beating & hauling around. If that didn’t work, the next step or alternative was the On & Clear button at the same time. Didn’t have to go there:) . I bought this, but I then gave it away soon after. The deal breaker for me was that the trig functions (sine, cosine, and tangent) are not quickly accessible. This calculator requires that you hit the “2nd function” button, then hit the Pi button that has trig as a secondary function, then choose from the menu, etc. For a student that needs a scientific calculator for trig, it’s best that sine, cosine, and tangent are their own buttons right on the keyboard.Edit: In regards to those who say trigonometry is not mentioned in the product description, students do complete basic trigonometry problems in Algebra 2, geometry, and science applications. The issue is not whether or not the student can complete trig functions with this calculator, it’s how inefficient it is. . This techn

ology is slightly newer than the wheel and flush-able toilet, yet our schools are still requiring the kids have one. There is a freaking free app on my 6th grader’s smart phone that emulates this thing, but he’s not allowed to use his phone in class. Maybe the US department of education should limit the length of contracts they make with industry partners to less than a generation!! . Pros:1. excellent calculator2. sturdy plastic construction3. perfect for 7th grade/Middle School math4. relatively inexpensiveCons:1. not really usable for higher level math, so an upgrade is likely in the future well before the lifetime of this calculator is near it’s end.I really didn’t want to get this but this was the best choice of the recommended choices from my daughter’s school for her 7th grade.I wanted to go top notch and get something that will last her not only for 7th, but all the way to college and maybe beyond. I mean, really, I bought her the “recommended” calculator last year, now this year this is the best of the “recommended” calculators, and next year, and the year after and the year after than I know how these things work. EVERY year, I will be buying her a new calculator. Why not just get the best right now and get it out of the way so I don’t have to waste time ordering/buying a new calculator every year? Well, I am still a little wary to put a $160 calculator in her hands right now (and she wants a $500 smartphone to boot) yeah right. Show me some serious responsibility and care for the items you have and then I’ll reconsider and get her the things she wants. I still have my calculators from middle school that I used in high school and then in college and yes, they still work.Remember one thing .calculators are not like cell phones that get upgraded each and every year. The latest top of the line TI calc is the same one they have been selling for TEN YEARS and you can still buy the same exact HP financial calculator that I bought over 30 years ago. Yeah, innovation and upgrades are not that common in the calculator industry. The only thing they do is change the exterior appears all smoke and mirrors.CONCLUSION: If you have a kid/s going to middle school (especially 7th grade) this could be the perfect calculator to get them. Just try to get on sale $20 is not bad, but I have seen this go down as low as $10 and that $10 savings goes a long way in buying other school supplies that you need. Read more

This can lead to statistical problems. Texas hardware scientific calculator TI-30XA can work. It is very easy when it comes to finding complex parts. It can add, subtract, multiply, and divide an item when it enters the traditional number / letter pattern. This calculator can also perform various conversions: from various parts to decimal, from degrees to radio signals to degrees, from DMS to decimal numbers and from polar to rectangular. The display screen contains 10 digits.\n\nIt\’s a great tool for high school or college students to solve tough math problems (and a gift for thought after school), and it allows more teachers to use the calculator during lessons and exams. , It\’s necessary. Easy to use and easy to fit in a bag, the TI-30XA will soon be indispensable for serious mathematicians and aspiring mathematicians alike. – Dana Van Nyst Top Reviews Â The quality has really dropped with these calculators. Very disappointed. It won’t accept any input with any of the buttons, and it won’t even turn off (no, it’s not the solar version). I’ve uploaded a video to show why this thing is junk. . Handsome design. Very solid feel. Cover too tight but I have an easy fix for that.Very easy to see or locate function keys and number keys.Key pressure has solid feel of durability. Would handle rough and tough treatment.Battery operated. Battery should last for years and calculator has an OFF keyDisplay clear with good contrast.Has a back arrow key to delete entry one number at a time Very nice Functions like delete keyand very visible and easy to locate. ( bottom left of calculator).Very adequate for algebra, trigonometry, calculus, chemistry, physicsHyp,Sin,Cos,Tan,Pi keys very accessible and visible.Purchase 600 grain or finer sand paper at hardware store. Tear off a small piece and sand the little “catches” on each side of the cover. Don’t overdue it because you can’t reverse the process. I did that and it slides on and off smoothly but still holds the cover on.I found that paying extra $ for faster delivery pays off! The packaged calculator travels with smaller and lighterpackages gets a lot less abusive treatment.CONCLUSIONTi-30Xa is a handsome,user friendly, durable, well designed calculator that is an excellent choice for GED test, algebra, geometry, trigonometry, algebra II, calculus, physics, and chemistry.I hope this review is helpful. . This is my first unsatisfactory review and it is hard for me to be critical. We did not open this until two days ago 06/09/2019 because it wasn’t needed until now. I went to check when I bought it and found out we purchased it in September 1, 2015. Go figure. Never expected a new product not to work straight out of the package. We did all the trouble shooting and it turns on but quickly becomes not usable. My son had to go borrow a friend’s calculator because he had an exam the next morning and needed a device he could rely on to work properly. I can’t expect the seller to honor this even though it was unopened all of this time. But I guess the lesson here is open and check your purchases sooner to make sure they work. . I ordered the product because the image is the same as the one that I needed to replace, just note that the one you will receive is not the same as the one in the picture. It is the same number TI-30XA, but it is a newer version (see picture, the one on the left is my old one advertised in the picture and the one on the right is the one that I received from my order). It would have received 5 stars if the cover slipped on and off the same as the old version, that’s my only complaint. The older version slides from the top down and the new one slides from the bottom up. Read more

Clearing the last entry and clearing all functions will help you get rid of errors quickly. Hard case included for added security. Slim and compact design. Top Reviews BEST scientific calculator for the price. I teach chemistry, and it’s particularly important to have an easy method to enter scientific notation. Casio has done this RIGHT, compared to the method used by Texas Instruments, which is not intuitive. This is the calculator that I suggest for all my Chemistry classes. . Good quality, form-factor, very visible display. Very “shirt-pocketable” dimensions.Unlike various other cheaper calculators, though, this seems NOT have HEX/BIN/OCT/DEC base conversions nor multi-base arithmetic. I would trade the stats function on this.Calculator works OK in dimmer light than other older models/brands. Would love if it allowed a backup coin battery (CR2032 or similar).Doesn’t take up much space in a packed briefcase.[If only someone would produce this exact calculator packaging, but with RPN logic and multi-base conversion/arithmetic, I’d be in heaven.] . This has all of the necessary functions for college statistics. Sure, it’d be nice to have a textbook view among other features – but this calculator does everything I would want & expect out of a <$10 calculator. It's a nice backup for my fx-CG50 or HP Prime calculators in the scenario of a dead battery in class. Slight learning curve to use fraction functions, but the included instructions are easily comprehended. It contains no batteries and is 100% solar powered. I've yet to have any issues sources power from various lamps and light fixtures from around my home. I'd highly recommend this if you'd like a simple calculator for your basic math - but if you are in a pinch - the fx-260 is highly versatile. I love that it has the stylings of the fx-CG50! . I used this calculator for years in adult education that I instructed. When my grandsons needed calculators, I was pleased to see that this one was available on Amazon. It has all the necessary functions for middle school/early high school math. A plus is that these calculators last for years. Great purchase! Read more

It reflects light in 3D, has a hard protective case, and is powered by solar and battery hybrid energy. Top Reviews This has quickly become my Favorite calculator !Especially enjoy the non-glare face & keys,as opposed to their EL-501X model.Tip:Replace the standard Alkaline battery (LR44)with a Silver-Oxide # 357.Longer battery life,with much less chance of Leakage ! . I own a Ti-84 Plus, but this EL-506TS gas become my go-to calculator for most everything. Yes the TI is more powerful (and programmable, which this calculator is not) but it’s also far more complex to use, with much wading through menus and submenus to do more than basic stuff. The EL-506 is much easier to use and navigate. I’ve owned the calculator for a couple months now and I’m quite happy with it.One feature I particularly like is the dual-power solar and battery. No need tochange batteries at inconvenient times.Although it’s billed as a 12-digit calculator, ten digits is more like it. The eleventh and twelfth digits show up only as the exponent in scientific notation.The biggest drawback, in my opinion, is the documentation. The sheet that comes with the calculator is an unreadable micro font. And this calculator absolutely requires a manual.The inside of the slip-on cover has the URL and QR code for Sharp’s support/manuals page which is at least readable. But a Google search can come up with a better manual, OperationGuide_EL506TS.pdf, on Sharp’s website.Overall I’m quite happy with the purchase. . A professor recommended this one for a statistics class, said it is easier than the TI, and he is correct . I use this calculator daily and has functioned as it should for over 8 months . I would buy another Read more

The calculator includes free memory, stable computing, a series of arithmetic operations, and more. Top Reviews Iâ€™m a math teacher, and I had a class set of these. Through years in use, I ended up with fewer than I needed. The other calculators I filled in with were harder to use, I got tired of kids arguing about who got the â€œgoodâ€ calculators, so I decided to get more of these.(My daughter is studying physics in college and this is the calculator she keeps on her desk.) . Can’t for the life of me figure out how to put the equal sign for an equation without it solving the equation. And, I cannot figure out how to put a greater or less than sign < or > . Read the online manual (pdf) and still can’t figure it out. I need to take a class just to learn how to use the darn thing. It’s nice but not easy to use . and not having a physical manual, in paper really sucks and is not convenient. . I had to talk my daughter into trying this calculator, as it wasn’t a popular choice in her class, but she loves how she can put full formulas into the calculator with fractions and decimals. Amazing ability to i

nput long formulas too. Great, cost-effective choice for non-graphing calculator. . I have been looking for a good calculator for my son, he is in 7th grade and pre-algebra has started. The device stores your last few calculations so you can go back and check them or use them again. Read more

### 11 – Texas Instruments TI-30XIIS Scientific Calculator, White

A basic two-line calculator combines high school math and science statistics with modern science writing. Top Reviews I bought this calculator specifically because it displayed fractions vertically instead of sideways as shown in the Amazon picture attached. Iâ€™ve also attached a picture of the calculator I received and how the fractions are displayed sideways. This is not what I expected and I will need to return it. Great Price for the standard scientific calculator though. . WATCH YOUR NEGATIVES. If you donâ€™t make sure your negative numbers are enclosed in parenthesis, this calculator will give you the incorrect sign! I also have found that occasionally when I try to put in a decimal the calculator doesnâ€™t accept it immediately and I have to do my calculations a second time to ensure the decimal makes it into the problem, which paired with the issue of negative numbers can be frustrating. Otherwise, this calculator looks nice and gets the job done as long as you pay close attention to what/how youâ€™re plugging numbers in and donâ€™t go too fast. . I really, really don’t like the fact that I was required to buy this calculator for a Calculus class that I never wanted to take, but this totally does what it’s supposed to do.I got the white one, which was totally a good idea for an extra $2 or whatever it was. I’ve seen it laying around several times and thought “I wonder if I lost my calculator ?” and then I check my bookbag and it’s totally mine. If you would prefer to not lose the one thing keeping you from having a breakdown in your math class, opt for one of the less common colors.People complement my white calculator all the time, and honestly out of my class of 200 college kids, I’ve never seen another one. . Well itâ€™s a ti30 calculator but itâ€™s not white. In fact itâ€™s sparkily pink or lilac. The picture shows a white calculator and Iâ€™ve seen one in person and thatâ€™s what I wanted but what was shipped is not white. For the price, Iâ€™ll keep it but itâ€™s NoT what I wanted. Disappointed.Update: Iâ€™ve seen at least two other people at school with one and it seems that they all have this somewhat pink tot them. Iits how they were manufactured. Iâ€™m starting to like the color a bit more. They are outstanding calculators so that was a never a problem. I do love that itâ€™s solar powered and that I donâ€™t ever need a battery. Read more

### 12 – TI-30XIIS? Scientific Calculator, Blue

Basic Scientific Calculator with Dual Solar / Battery Power Line Top Reviews It adds, subtracts, multiplies, and divides both integers and decimals with precision accuracy! It has lots of extra functions to keep parents amused while their child asks “hey, what does SIN do?” It’s everything a parent hopes for when purchasing their child’s first SCI Calc.Seriously though Heading into her first year of Algebra, my daughter needed her first scientific calculator. This is the model they use in her class so I decided to get her one for home use. It’s obviously not as full functioned as a full-on graphing calculator (I pulled out my trusty old TI-85 for comparison), but it’s got everything she should need for the next few years of algebra and geometery. The solar cell works great on this. At night, indoors, the screen is still strongly visible and its nice not having to worry about batteries. This is a great tweener calculator. . This little calculator managed to do was some of the bigger ones do that half the price. Dual line display solar powered and fashionable what else can you ask for? I got these for my daughters for their junior high and high school classes. I actually just rebought these ones as one was lost and another stolen. Heck, these are so good other students are stealing them, I mean how often can you say my calculator so good other people stole it because itâ€™s better than theirs?You canâ€™t! Itâ€™s just that good! . This is my favorite TI calculator. Itâ€™s simplicity and weight are absolutely wonderful. Testing center friendly and great for college course work when graphing calculators are forbidden. . I include these in Christmas Shoeboxes through Samaritan’s Purse last year and this. I taught engineering for twenty years, and these are adequate for any math through Calculus, and don’t use batteries. I always carried one in my briefcase on business trips as a backup. Great for the money. Read more

### 13 – Texas Instruments TI-30X IIS Scientific Calculator ï¿½ Pretty Pink

The TI-30XIIS Scientific Calculator is approved for use on the SAT, ACT, and AP exams. Ideal: general mathematics, pre-algebra, algebra 1 and 2, geometry, statistics and general sciences. Top Reviews I purchased this calculator because it is required for my chemistry courses in college. I am a return student, and I remember how rampant theft was/is on college campuses. I also happen to be somewhat absent minded and sometimes leave items, like this calculator, on the seat or table where I was last using it. Well, I didn’t want to have to replace this ever, and just writing my name on it didn’t seem like it would be enough (college students rarely care about that sort of thing) so I decided to get the worse color possible. The color that no one actually wanted to be seen using. Thus the purchase of the bubblegum pink calculator happened.I’m happy to say that it worked! I have accidentally left this thing in the classroom, as well as in the library and the food court on campus MULTIPLE times, and it is ALWAYS there when I return to collect it.This awful color has made this calculator totally theft proof. It’s seriously everything I could ever have wanted from a calculator. Even my husband won’t use it at home when there’s no one else there but him.Absolutely pleased with my purchase, and hopefully I will never have to purchase again!Oh . the calculating part works great. No issues there either. . I had to buy a new calculator for my class because graphing calculators werenâ€™t accept. I saw this one for a decent price, and bought it. I like it! It works like a normal calculator, which is good for any math that doesnâ€™t include graphing, essentially. Works well and turns off by itself after a few minutes without use (which is a plus because sometimes I forget to turn off my calculators and the

batteries run out really fast) . I absolutely LOVE this calculator! I used it in my statistics class and also used it in algebra. I would definitely suggest purchasing this for your college or high school student because becoming more familiar with the commands and shortcuts helped me immensely! And I don’t believe it would be easy to learn or remember without owning it and being able to play with it on your own. . As a teacher in a Community College Developmental Math program I have nothing but praise for this calculator. Best investment for anyone in Pre-Algebra and beyond. Read more

### 14 – Texas Instruments TI-30X IIS Scientific Calculator, Blue

The Texas Equipment IIS TI-30X Calculator combines cutting-edge scientific data and functionality in one attractive package. Durable and suitable for classroom, home or office use. A two-line screen helps students learn math and science in the classroom. Pink, this calculator from Texas has double the capacity of data and components. It displays records and results and also has the ability to remember and edit previous records. Texas Equipment TI-30X IIS Calculator: Top Reviews Had this style calculator for years. Has most functions that this engineer needs in an easy layout. Liked it in my 20s and appreciate it with my older eyes in my 40s. My old one was still working fine but I lost it. . I got this for my high school math class and it works perfectly. It has never not worked and is very easy to use. I don’t know how to remove the problems that you have already done after you cancel. because you can hit the up arrow and it will go back to a past problem you have done. The color is a nice blue and not boring. Great overall product. . My child needed one on her supply list for Jr. High. This is the exact one listed on the supply box kit list. It was $4 cheaper on Amazon so it was a no brainer. . This is exactly what my son wanted for his classroom work as requested by his teacher. He has been using it since I bought this for him. So far, he hasn’t complained one bit. His response is that it works. 🙂 Read more

### 15 – RENUS 8 Packs, 2-Line Engineering Scientific Calculator Function Calculator for Student and Teacher

Size: 8pcs | Black color\n\nRain 8 packages, 2 for students and teachers. Scientific calculator, linear geometry, function calculator Top Reviews I purchased these calculators for use in a high school math classroom, specifically for their exponential and logarithmic capabilities. They are easy to use (layout is clean, functions and mode changes can be found intuitively). I am specifically pleased by how sturdy the calculators seem — I expect they will hold up well against classroom (ab)use, and the construction of the lids gives me the hope that students will have a harder time wedging them on the wrong way (a frequent occurrence with flimsier lids). Another excellent feature for classroom use is that the calculator shows the operations and syntax of the entry, not just the answer (which is helpful when students don’t know why they’re not getting the right answer). They came with batteries (always a plus), and the batteries required are a standard size (AAA), which will be a nice feature when battery replacement becomes necessary. . There is technically nothing wrong with the products but I wound up going to a 99 cents store in town for some candy for my class and just so happened to see the exact same calculators for 99 cents each. I spent way to much money purchasing them here and it took to long to get them. I should have looked at the 99 cents store first. . 2 line display, easy one button exp (scientific notation), uses AAA batteries. Great alternative to a $14 TI model. I bought 8 of them for my Chem classroom. . Good deal. Basically 2 for price of 1. Keys are larger than most and readout is large enough to see clearly. Good case keeps keypad clean. Read more

### 16 – HP 35S 35S Programmable Scientific Calculator, 14-Digit LCD (HP-35S/B12)

HP 35S 35S Programmable Scientific Calculator, 14-Digit LCD Top Reviews Meets expectations but really bummed that they limited the stack to 3 deep. My 48 GX really spoiled me, but had to have this one for PE exam. Would warn everyone that there is no warning that you have exceeded the stack. It will give you an answer but t will be wrong. This is likely not an issue unless you have been accustomed to the much larger stack on the 48 GX. . This is my fourth HP RPN pocket calculator. My first was an HP 45, purchased in 1974 (and cost more than I paid for my first car). Not programmable, but wildly useful. It still kinda works, but only if plugged into the wall. My second was an HP11C, purchased in 1980. A fabulous calculator, in all ways! It still works, but I have to pay attention to each keystroke as sometimes the buttons fail to register. Its integration function/algorithm, however, beautifully replicates analytical solutions. Not so my third calculator, an HP 32SII, purchased in 2001. Its integration function was faster and usually ~10% less accurate than the HP 11C (i.e., doing the same integrals and comparing to the analytical solution). The HP 32SII has failed completely, specifically the buttons: they simply do not work anymore, period. So it has been replaced with this new HP 35 S. The integration algorithm is surprisingly bad! Breaking up an integral into smaller and smaller parts (and then summing the solutions) gets closer and closer to the analytical solution, but what a pain! The other problem is it’s an RPN/Algebraic hybrid (i.e., all but a sellout, philosophically). The owners manual only presents programming examples in algebraic. This wouldn’t be a problem if the RPN programming protocol was left unchanged from previous HP devices, but, of course, it wasn’t and I’ve had to screw around figuring out the changes to get my programs to be implemented, as the manual is of little use. I’m glad that I still have my 11C, but after 39 years of service (more lightly for the past ten, but, hey!), it will fail completely sooner or later. So, to HP: bring back the 11C, manufactured at least as well as the original! In the meanwhile, I’ll slog along with this 35S, wondering about the quality of my integration results . . Typical HP genius- Easy to get functional on, but you need two PhD’s to understand all the functions. Never mind, it can do the things you understand, also.RPN is a different syntax that allows no confusion around which thing comes first in operations, or is paired with what. No parentheses. Yet you can enter the most complex expressions right

into it, get your answer, and poke on and on, nesting equations, and appending the answer to the ongoing result value, many layers deep. You should really learn this. You’ll never go back. . If you don’t know how to program a calculator for repetive calculations, begin on this machine. If you don’t know RPN calculator operations which are far faster and less error prone than “=”, buy this and learn. You will be thrilled. The LCD display reads nicely in direct sunlight as well as at a dim desk, any angle. The calculator will not run a remote printer so far as I know. It is very fast for chained entry. Just keep an eye on what you are doing.Key printing should be OK for a few years if your hands are clean. These don’t look like molded-in or laser-etched markings so beware lifetime if your hands are abrasive. Passes anti-functions tests. Very nifty units conversion on keyboard. Excellent solver function entry. The keyboard is much better than using a cellphone and app. The programmability is the icing on the cake. Read more

### 17 – Sharp EL-1197PIII Heavy Duty Color Printing Calculator with Clock and Calendar

Product description\n\nThis 12-digit calculator is ideal for the modern user, especially in a busy office. Enhanced stability, ideal for advanced users.

The keys have antimicrobial protection that reduces the growth of germs and bacteria that can cause pigmentation and odor. Professional keyboard layout with left summary key. 4-key free memory with second memory function. Amazon.com\n\nThe Sharp EL-1197P Roller Print Calculator is an indispensable tool for tough office environments. The EL-1197P has a large 10-bit blue fluorescent screen and hides letters in black every second for 3 seconds on standard rolls of paper.\n\nThe EL-1197P includes four main memories (extra memory, minus memory, and recall / clear) and dedicated function keys, including grand total, end mode, fixed, double zero, profit / profit, item counter and external settings. Count on free Shark memory for stability. Decimal settings are adjustable from floating to fixed decimal (6-3-2-1-0). From the developer\n\nThis printing calculator has a bright green fluorescent display with 3-digit punctuation.

There is also a power switch with a print / count mode selector and a decimal stop adjuster. Set the Permanent / Add and Grand Total / Total options. This mechanical printer accepts paper rolls from 57mm (2-1 / 4 \) to 58mm (2-9 / 32\) wide and a maximum of 80mm (3-5 / 32 \). 3. Prints 3.6 lines per second. 8-31 / 32 \wide, 12-3 / 8\ deep, 2-25 / 32 \high, 3.75 lbs. Top Reviews My FAVORITE calculator of all time! In acctg, you are as good as your tools and this is my fave. Total button at the thumb. :-)Update: here’s a pic with dimensions. The paper is fully extended . Also for those who have questions about the decimal point; if you do not want to constantly hit the decimal while you are adding, use the pic and set yours that way.It will automatically put in the decimal to look like this 0.00. . I expected heavy duty to include a heavier touch on the keys which it DOES NOT HAVE. It is good and heavy otherwise. I am still adjusting to using it. I have tried many features to see how they work. I bought it to balance my checkbook and have a print out. I thought it would keep a balance while using sub total but you have to keep adding the sub total in to continue. I had one like this years ago but I do not think it worked this way. I really like the easy to see screen! It is a huge help.Overall satisfied and would recommend this to anyone looking for a machine that does not move when you touch it! If you have the need for all these extra features they are also a plus! Still wish there was a heavier touch of the keys. It would help to keep your fingers where they need to be. Came with a tiny roll of paper.Shipping was slow, but that was ok. I choose free shipping and ground service. Both boxes were intact and in good shape.It will be in use for many years to come! . Sorry, thought I had already done the feedback! This is a wonderful machine – I just use it in my tax business .I know, using a mechanical adding machine when you already have a computer, well its more than that to me. I’ve been in the tax business for over 40 years and not once during those years did I not have a calculator on hand. Or for that matter, an IBM Selectric Typewriter – not sure I could do my job without both of these “old style mechanical pieces”. Thanks guys – great machine at a very reasonable price. . This unit replaces another Sharp calculator which finally expired after more than 20 years of hard service. This unit is almost the same, but unfortunately, nothing is made as it was years ago. Manufacturers have found it advantageous to make everything lighter, thinner, and generally more cheaply, and the quality is not as good. On the other hand, at least out of the box, this calculator does exactly what it is supposed to. The keys are arranged in the right place for me (some manufacturers seem to have the keys in rather bizarre arrangements). It is also fast and quiet and compact without being cramped.Importantly to me, the feel of the keys as you input data is good. The keys themselves, and their distance from each other, are comfortable (I personally do not like the sculpted Chiclet-like keys that butt up against each other; for me at least, those keys tend to encourage physical slips that result in incorrect entries). The Chiclet keys also seem to have a short distance of travel; in other words, you do not and cannot press the keys very far. Some might find that an advantage – I like to be able to depress the key for what feels like a 1/4 or so. This gives feedback to your brain when you are entering data (particularly in a hurry) that you have actually made the entry. This unit provides that feedback.My much-missed older printing calculator described above cost several times the price of this one, and I would gladly pay that price again for the heft and quality of the unit, but no one seems to offer anything similar.I was going to rate this unit 4 stars, because it is not perfect. But is does all the basic functions well – and then some. From my extensive explorations of what is available, I don’t think there is a better unit out there, and some are offered at two to three times the price. Read more

No instructions so if you buy be prepared to figure it all out2. The case/ screen protector is extremely hard to take off so donâ€™t put it onOther than that itâ€™s a calculator . it works nice price . The calculator does what itâ€™s supposed to do. The cover is hard to get on and off sometimes. Thereâ€™s nothing that came with it such as a booklet to let you know what is what. For the folks not so mathematically inclined it can be a bother. It doesnâ€™t compute percents using the percent key. Thatâ€™s the most frustrating part of it. . I used it for my Statistics exams at college and it is a great calculator. Very light and easy to use. It has basic and advanced features too. . I had to get this calculator for chemistry class because they donâ€™t allow graphing calculators.
