1 – Sharp EL-531WHBK Scientific Calculator
Top Reviews I was issued this same calculator as part of materials in an online course, after 10 yrs never had to change batteries, but the buttons were worn-out. it is the next best thing for introductory statistics and algebra calculations, compared to a graphic calculator which is way more expensive if you are only planning on taking a couple of introductory classes. So glad I was able to find it!! Thank you. Last used something like this for more than 10 years. Great to know the brand is still as good. Great functionality if you take the time to learn how to use it. Highly recommend! Love it! . I am used to a HP 17, but I needed a simple calculator to use at work. I wanted the parenthesis function though, and this one has it. It’s easy to read, use and is very practical. Serves my purpose perfectly. Read more
2 – Sharp EL-531XBGR Engineering/Scientific Calculator
Top Reviews The battery terminal contacts are faulty. The metal terminal looses its stiffness after a few days of installing the battery. This causes a poor contact to the battery such that the digital display fades away and eventually the lcd screen turns off. Removing the battery and re-shaping the connector allows the calculator to function for another 24hours before the same result happens. The battery used has been measured at full charge of 1.5V using a multimeter, to eliminate one possibility of error. This item is faulty in the calculator caused my child to be penalized during an exam as the calculator had failed midway during the exam. Very disappointed. . The display has a narrow viewing angle so you won’t be able to see it depending on where you’re sitting. The buttons are a little loose too. I knew both of these things before buying and still went with this one because the color was nice (haha).In my opinion, it was worth it, but these things could still be improved upon. It’s still a functioning calculator and is relatively easy to use. . This is the fifth or sixth time I have purchased this calculator. The first five were borrowed by my co-workers and not returned. I donâ€™t mind because the calculator is inexpensive and stands up to the abuse of a construction site. . I had before similar to this, but unfortunately it’s way different to read Read more

4 – Sharp EL-520XBWH Engineering/Scientific Calculator
Top Reviews This little thing has an impressive array of functions. I use it to cross-check some of my math in linear calculations and it has proved invaluable. An added bonus that I did not expect is the ability to work in binary, hex, or octal as well as base 10. I usually convert binary to base ten for math and then back again. Now I just enter the binary numbers directly – cool. The only thing that has kept this calculator from getting a five-star rating is the color choices that Sharp made. As in most scientific calculators, each button can have multiple functions. Sharp chose to make the faceplate black and the printing for alternate functions in dark aqua and dark rust. Don’t expect to use this calculator anywhere with less than optimum lighting. Even sitting by a lamp in the early morning, I could not see the key markings to do my work. This calculator is great. Even though it is solar-powered it has a very readable screen in even dim lighting. The only thing I don’t particularly care for is the fact that when you are trying to find the power of a negative number, it will automatically put the negative number into parenthesis. The blister cover was already separated from the paper backing, but the calculator appears to be in perfect shape. It has the hex-oct-dec-bin conversion function keys I needed and seems to have a lot of functionality for the price. I don’t like the feel of the keys–they feel flimsy and lack the positive click feel that I’m used to with TI calculators. Can’t beat the price – $10? Are you kidding me? Got it because it shows all my factors on top-line beside the answer. Good show! Read more
5 – Sharp EL344RB 10-Digit Calculator with Punctuation, Metric Converter, Solar Powered LCD Display, Small Pocket Calculator for Students and Professionals
Top Reviews First and most important is the dimensions they list on Amazon are twice as large as the actual calculator. The keys and screens are way too small. I bought based upon listed measurements.Second, I need metric conversion. Guess what? It does have a millimeter to inch conversion. That is what I use every day in my woodshop. OMGThe actual dimensions are: 4 11/16 high & 2 3/8 wide. That is far short of the stated: 7.5 x 4.63 x 0.5 inIf you want a dinky calculator with metric missing millimeters, then go for it. This solar+replaceable battery 10 digit calculator replaced a failed earlier model I’d used happily for a decade. This new version includes two powerful additional abilities: metric conversions and decimal to fraction conversions. Unfortunately, the added abilities are not completely intuitive for an infrequent user like me, so I’d have preferred doing without them in favor of a bigger display or battery. That said, it’s still the best small and thin more-than-eight digit calculator I could find now, and so long as I keep its manual handy I can definitely do lots of useful new things with it not possible on earlier models. Happy circumstance: I remember enough arithmetic from my school days, to do basic calculations with pencil and paper, or in my head (cashiers are always amazed 😎 ).But as an American interested in European and world affairs, the calculations I cannot do easily are: American measurements to Metric, Metric to American. A never-ending source of annoyance.This little calculator solves the problem very well. Must own 4 of them (2 I can’t find: also annoying).My only criticism would be: the labels for the various types of calculation can be difficult to read because I have to take off my glasses (very near-sighted, and getting to an age, sad to write ).Definitely a Don’t leave home without it! gadget. Also much handier than the iPhone. Wow! This Sharp EL344RB calculator does everything. It can actually calculate fractions. And it can mix decimals with fractions. It also has metric and USA measurement conversions, as well as foreign currency, buy/sell conversion. For a small calculator, it has a large display. Many other calculators lose their currency conversion entries after they time out. Not this one. You can pick it up 2 days later and it still has your foreign conversion detail in memory. It also has a constant multiplicand – great for figuring your net pay without repeatedly entering the Gross amount. It has dual power and comes with a nice folding vinyl case. This is not a complicated device. Some of the features are not intuitive, but within 30 minutes you can learn all of the features. No engineering degree from MIT required. Any 12yr old with a half a brain can use this, It’s quite accurate.it’s calculations are always correct. In fact, it’s a great toy. I’m always trying to fool it. For the price, a bargain, without having to drag out my laptop or tablet and call up the correct apps. I wholeheartedly recommend this calculator. Read more
