1 – Texas Instruments Nspire CX CAS Graphing Calculator
Top Reviews Great calculator. Crappy company.Display failed before the 1 year warranty was up. TI says it’s physically damaged (dropped, excessive pressure, got wet, etc) and therefore is not covered. Calculator was well cared for, never dropped, got wet wet, etc Owned many TI products going back to the Speak & Spell including multiple TI calculators (TI 84 Plus CE, TI CX, TI 36X ) always very reliable. This is the first time actually trying to use the warranty. Seems like their customer service has been engineered by their finest team of accountants. Shame. . This is the best calculator that I have ever seen for sale and will serve well for anyone that is not barred from using computer algebraic systems on exams. If you are looking at this, you probably have a fairly good idea of why you may want a CAS calculator. Symbolic manipulation is quite good and pretty easy to use once you play with it for a few hours. I see no reason why the non-CAS version of this calculator even exists except for the sole purpose of being used for standardized testing.Battery life is actually better than I expected coming from a TI-84 running on AAA batteries that lasted a few months at a time.There are a few limitations on this that should be noted. It is not possible to work in the S-domain or Z-domain. Laplace and inverse Laplace transforms as well as Z-transforms cannot be done natively. Using the definition of each will obtain a somewhat close answer but as the unit step function is not a recognized function, hand solving for these types of problems will yield the correct result faster than attempting to use the calculator.An annoying software issue is that it is slow to change settings for a specific document/scratchpad that is open. Changing from degrees to radians or floating to fixed decimals takes around seven or eight button presses. Hopefully Texas Instruments will fix these shortcomings, but I do not foresee any substantial updates within the lifespan of this model.In short, buy this if you are allowed to use it and need a capable calculator. It does the job even if it takes a little while to input certain types of problems. I don’t think there is a better option available on the market at this time. . For better or for worse, TI has a near monopoly on the educational market. Needing a graphing calculator for my high-schooler, I researched the venerable TI-84 series and settled on the new Nspire CX CAS. Coming from an engineering background, I actually used the HP48g series; however, because the use of TI calculators is nearly ubiquitous in high-school and college, I knew I had to get a TI calculator.The NSpire CX CAS is an excellent calculator. It supports nearly everything that a Algebra 1, Algebra 2/Trig or Calculus student would need. The CAS (Computer Algebra System) system allows solving, expanding and factoring of algebraic equations symbolically. This is a great boon for students wanting to check their work. My son does the work by hand (which many teachers require) and then will check the final result using the solve function. Solving for roots of quadratics is as simple as entering solve(Quadratic,variable).The best thing about this calculator is the PC software it comes with. When my son is doing his HW at home, he is able to use the PC and very quickly enter equations and check his work. Much faster than he would be able to on the calculator at school.The calculator comes with a large library of built-in math functions, as well as the capability to plot graphs (including inequalities). It also has a built-in spreadsheet where one can perform plotting of discrete points and even allows one to perform a linear regression on the points. The calculator comes with a tiny getting started guide, which is almost useless. You will have to go online and download the real PDF manual from TI to be able to understand some of the basic functions of this calculator.Overall, this calculator is much more advanced than the HP48gx I used when in Engineering college. I do however, prefer the RPN of the HP calculators. The CAS system is a very nice added touch, and unless you need the calculator for the ACT test, I would recommend skipping the non-CAS version and spending a few bucks more to get the CAS functionality. . The TI Nspire CX CAS is the absolutely hands down best calculator on the market today. I have owned a TI-85 84 84plus 89 and 92. I have also had the NSpire CX (NOT CAS) This was by due to its acceptance on all standardized testing. The CAS version is not allowed on ACTs but is allowed on SATs. The big difference is the CAS has computer algebra solver. This allows it to solve linear equations which is a huge difference. They are hardware wise the exact same calculator, but the CAS version is absolutely more powerful. Amazon has them for ~130 and thats a steal from what they used to cost. This is by far the best calculator I have ever used. If you are not used to using TI graphing calculators there is a learning curve, however there are countless online tutorials and YouTube videos and TI even has an in-depth manual available as a PDF. This also comes with the student software included in the price. It works on MacOS and Windows. It allows you to use all the functions of the calculator on the computer and more. If you are taking a course which needs a graphing calculator this is the ONLY option you should consider. Read more
2 – Protective Case for Texas Instruments TI-Nspire CX II/CX II CAS
Top Reviews I ordered this case and it does not fit the TI-84PLCE graphing calculator. This case is 1 1/4 inches too short for the calculator. I double checked that I ordered the correct case and I did, which I returned. Please beware this case’s measurements/site is wrong. This case was 6 1/4 inches long and the calculator is 7 1/2 inches in length. . While it is true that the Texas Instruments TI-30XA has a built-in sliding cover, it is equally true that kiddo has a remarkable ability to find new ways to break things. Hey – that may be a future summer job, product tester/destroyer. Anyway, we don’t want the calculator destroyed as kiddo needs it for algebra, so in a belt-and-suspenders approach to protection, we have acquired this case. The calculator fits within nicely, the shell is fairly sturdy but soft, the zipper appears to be robust, and as long as kiddo doesn’t lose it (another great skill), the calculator will enjoy greater protection. The case could also be used to hold a smaller phone, an external battery pack, a pack of playing cards, a power adapter, or any number of other devices that we need to carry around. . Fits the size calculator as stated. Sturdy shell not flimsy. Could be used to carry anything really. . This seems like it will last as a case for my 12 year old son’s calculator. We will see but I am hopeful! Read more
3 – Guerrilla Military Grade Screen Protector 2-Pack For TI Nspire CX, CX CAS, CX II, and CX CAS II
Graphing Calculator
Top Reviews I have bought products from Guerrilla before and never been let down until now. I own a TI Nspire CX CAS. This is the recommended screen protector for my calculator and it does not fit. There is about an eighth of an inch overhang on the top portion of the screen making the screen protector more likely to fall off or peel of unintentionally. Good thing there are two screen protectors because I ruined the first trying to make it fit. With the second screen protector I found out I had to alter the screen protector by cutting both sides of the bottom edge so it could fit around the esc. and on buttons. After it was cut it fit better although It doesn’t look as nice as a product specifically made for a product. From my picture you can notice the screen protector is aligned on the top properly and the bottom has been cut. Also the middle area of the bottom is pushing up because it is still not altered enough. Very Disappointing. . Trash.1. Unlike cellphone screen protectors that are glass, this one is a cheap plastic that should cost ten cents IF it worked, which it does not (see below).2. The size is wrong; it is too big for the TI nspire CX calculator for which it is advertised.3. Instructions provided on the outside of the box are insufficient.Sadly, once one has tried to use this useless product, there is nothing to “return for refund”.All in all, a piece of trash. Do NOT order it. . Too tall It fits width of screen but like others is about 1/8″ too long on height. This should be an exact fit for my TI Nspire CS. Trimming it may be possible but I didn’t buy a CUT TO SIZE item. 1 Star for false advertising. . The thing is too long for the TI-Nspire that it is supposed to fit. It hangs over the end of the screen about 1/4″. You can always cut off the overhang, but c’mon, you just forked over 13 bucks for two pieces of Saran Wrap made to cover a calculator that does calculus and trigonometry. They could at least get the measurements right. Read more
4 – Texas Instruments Ti Nspire Cx Cas Graphing Calc
Top Reviews My son loves this and finds it very helpful in his math classes . The calculator is amazing! I rubbed it in all of my nerdy friends faces for months. Unfortunately the software key that came with it was already used and that is NOT OK. . Fast delivery, good product! . Da ingegnere, consiglio pienamente questa calcolatrice a tutti quelli che studiano o lavorano in ambito matematico. Potenza di calcolo paragonabile ad un programma come Matlab, ma estremamente più intuitiva e rapida nella scrittura dei calcoli. Non posso non dire che mi sono laureato anche grazie a questa calcolatrice, accorcia notevolmente i tempi di calcolo rispetto ad una calcolatrice normale. Mi sento anche di dire che è addirittura sovradimensionata, sempre come capacità di calcolo e funzionalità , per la sola facoltà di ingegneria. Prezzo alto, ma vale fino all’ultimo centesimo, da considerare come investimento anche per un futuro lavorativo. Read more
5 – Texas Instruments Nspire CX N3/TPK/2L1 Spot Teacher Pack
Top Reviews It’s in a great shape,and works great, thanks . The TI Nspire CX is a very powerful calculator, and it’s well built to hold up to the wear and tear of daily use. . It works great, no issues at all with the calculator. The calculator is in great shape physically. . BUYERS BEWARE! The picture is a Nspire CX but the description says its only for TI84s. This is false advertising Read more
6 – Texas Instruments TI-Nspire CX Graphing Calculator
Top Reviews The calculator does everything as promised with a few caveats. The OS can be slow at times. The screen is not the easiest to read in sunlight. And the unit could use beefed up a little bit, it seems flimsy compared to older TI models. But TI seems to slowly over time address user issues with hardware and software updates.I do wish they would have made a single model with CAS, and allowed the Push-to-Test function disable the CAS feature. This would prevent people from having to choose between a full featured calculator, and one that is not often allowed in classrooms and some standardized tests. But this issue may likely be influenced by educators and test makers anyways. Still seems like an easily remedied problem. (And you can upgrade non-CAS models to the CAS software, and other workarounds to enable additional features. These solutions however are not officially supported by TI, and are done at your own risk.)My final word is with the supplier of my used model, it was listed at $110 vs ~135 new, shipped by Amazon, and labeled as acceptable. The model I received was well worn and 7 years old! Far too old to be marketed at such a high price. Several updates to hardware, including the processor, screen, and battery have been made since then. I would have accepted a model 2-3 years old at most but 7 is ridiculous for that price. If you look at the back of your calculator, the last four numbers show the month and year of manufacture. My picture shows 0411A, which would be April 2011, A representing the first batch ever made. Current models have gone through the entire alphabet and are now on to AA, AB, AC, etc. Models ending with letter O or greater have all relevant hardware upgrades FYI. . Admittedly somewhat disappointed in the product, however I’ll start with the pros.I love the backlit color screen! One of the main reasons I got another calculator was due to working later at night and needed more than adequate light to see my original ti-nspires screen. Being a non cas variant also allows me to use this on tests which is a plus. Having owned a ti-nspire in the past, the controls were quick to pick up. I like being able to charge the battery, instead of expending AA or AAA’s. The calculator is just as zippy and I think it serves all of its purposes nicely.The biggest grief I have with the product is the build quality. It feels like it was built from cheap, thin plastic. The calculator itself is unreasonably light, the clicks although audible leave something to be desired. You have to push relatively hard on each switch to get the input. The keys roll left and right, which just screams poorly made, as if they couldn’t make them the right size for each hole. Theirs a sizeable gap around each side of the touch pad and I can actually see the board underneath. The cover
snaps on way too tight, and I feel like I’m going to break the calculator from trying to pry it open. It just feels like a cheap plastic toy to me which is the complete opposite of my original ti-nspire cas.Considering the price point that these sit at, I think we can take a step in a better direction. I understand cutting back on weight a little as the original ti-nspire is a brick to hold, but it fits well in your hand and it feels like it will last me a lifetime. The buttons have a soft tactile feedback with each push and I can’t stress this enough, the buttons actually fit their holes. It seems like such a simple thing, but it shows that they took their time with the design. You see this type of quality in cheap $5 calculators and even those often times get it right. . I bought this to replace my TI-83 Plus. So far I am really happy with it. There is a bit of a learning curve at first when trying to find out where everything is. I do like the color screen and I like the lithium rechargeable battery. The battery last a very long time on a charge and it can be replaced by unscrewing the one screw to the battery door. The only annoying thing so far is the screen has a slight flicker when it’s at the lowest screen brightness.The package includes the calculator, a calculator cover, a USB to mini USB cable, a USB to wall adapter, a mini USB to mini USB cable (for syncing calculator to calculator), a CD with a manual on it and a card with a product code for the TI software. I attached a photo of all the contents and the box it came in.I would highly recommend this as a TI-83 replacement. . Great to save documents and pics but it takes alot of time to read it.Computer transfer, but does only support .tns documents so thats not so good.i think its a really good calculator have many functions. but they should make it faster in document reading.

7 – Texas Instruments Rapid Charger For Texas Instruments TI-Nspire, TI Nspire CX, TI Nspire CX CAS, TI Touchpads, TI 84 Plus C, TI 84 Plus C Silver Edition
Top Reviews This was not the product that was shown in the picture. This was just a generic charger without any Texas Instruments branding or appropriate regulatory markings. When I plugged it into my TI nspire Touchpad model, the battery indicator showed 0% and then “Critical” once I unplugged it after test charging overnight. . I bought this to replace the charger that my grandson lost. It works perfectly with his TI-84 Plus CE. . My daughter’s calculator stopped working and somewhere online I read that it might be the charging cord. I’m really glad I ordered it because once I plugged it in with the new cord, the calculator started working. Saved me over 100.00 for a new calculator! . It’s pretty much identical to the charger my TI-nspire CX CAS came with years ago. I needed a new one after my original cord started to break near the usb, and this one charges the calculator just fine. Read more

9 – Guerrilla Hard Travel Case for TI-83 Plus, TI-84 Plus, TI-84 Plus Color Edition, TI-89 Titanium, TI-Nspire CX&CX CAS,HP50G Graphing Calculators + Guerrilla’s Essential Calculator Accessory Kit, Black
Top Reviews What a great purchase! I LOVE this case. It is a hard case in bright pink! I purchased the Ti-84 plus CE Texas Instrument scientific calculator for my chemistry class. I tend to be a bit clumsy and drop my devices (phone, tablet) all the time. This case holds all the cool accessories it comes with along with the ti-84 and the cords! I’m very impressed. There’s even a divider between the calculator slot and the spot for the cords. I was hesitant on spending $40 on a case but when I spend $140 on a calculator, I want it protected. This case is worth every penny! The best part is it matches my pink calculator!! . Case: I have used this case on a near-daily basis since I purchased it two years ago and only recently did it begin to show wear. The case has outlasted two backpacks and has taken a good beating from being stuffed in with textbooks, dropping, and constant opening and closing. The only issue I’ve had since I got it has been with the zipper. The zipper has always been a bit tighter than most, which is a good thing when it’s protecting a $120 calculator*, but some might find it irritating. About a week ago, the zipper began sticking in one of the corners and refused to close. When I looked more closely, I found that one of the zipper teeth was coming out of place (it was shifting from its proper position). I fiddled with it and a few of the other teeth and I was able to close it. This happened a few more times when I was trying to close the case. It ended up getting completely stuck one day and I tried to force it to move. After a struggle, the zipper came off one track and some of the stitching on a few teeth came unattached from the case shell. This would have rendered the case useless but wait! There are two zippers! Since I had exclusively used the one zipper when opening/closing the case, it had worn out. But because there were two, the case will still work just fine and continue to protect the calculator.Accessory Kit/Features:Elastic Strap – It’s kept my calculator from falling out when I’ve forgotten to zip up the case. Works well and fits the calculator.Storage Area – I’ve kept my charging cords in this pocket.Pencils – I used them a few times but they were larger than I prefer and I found the balance to be less than ideal. I also couldn’t figure out how to put lead in them for the longest time (which also contributed to my not using them). Turns out you unscrew the bottom end and then the mechanism will come out. They’re not like normal mechanical pencils, as they don’t have erasers (hidden or in view) and they’re shaped more like a thick pen than a pencil. They also lack finger grips, so it’s easy for them to slip out of the hand.Eraser – Never used it, it looked too nice. I think it would do a pretty good job though, the material feels decent.Lead – 0.7mm, which I don’t like to use. The provided lead was a bit softer than I prefer, but that may just be because it’
s thicker than I’m used to.Graphing Ruler – I used this a lot when I was doing Algebra and Trig, the axis stencil is really nice when you’re first starting graphing, and the different function shapes are useful for reference when you’re just learning them.Overall, it’s a great kit. If it were a create your own kit, I’d change out the pencils, lead, and eraser for my preferences, but the way it comes should be fine for most people.*I have been keeping a TI Nspire CX Cas in this case. . When the case came in, I was very pleased with the overall toughness of it. The zippers are very crisp and always close tightly without any sort of looseness. There is ample room within the case for my calculator, its cables, and the charging adapter as well as a few small extras. I was very impressed with the quality of the other extras included, especially the X-Y Axis Graphing Ruler. As a college student majoring in two STEM areas of study, I trust that this case will protect my TI-nSpire CX CAS. The only problem that I have with the case itself is the lanyard which comes with it. The “metal” construction of it was very weak and it already broke after a few days of use. Besides that, I am very happy with the product. . Good hard case, but very big. Kinda embrassing to walk around with it but good to have it in a back pack so it won’t get smashed by books or laptop Read more ~~ best calculators ,
