Review: Best inexpensive calculator - Perfect in every way. Easy to read, super easy to operate, it is NOT a complicated calculator with a bunch of stuff you'll never use. And the main total/add, plus/minus multiply/divide keys are where they belong, on the far right side! note that many calculators put those one row away from the outer edge rather than ON the edge, and it is just easier & quicker in my opinion to calculate your totals by smacking keys on the edge rather than having to hunt for them in the middle of the keypad. Works in dim light too, compared to other calculators I have used it doesn't seem to need the "full brightness" others require. And it will last you for years. My last one gave me at least a decade and would still be going strong if I hadn't broken it. Looks nice too.
Review: Great basic calculator (and it does have an off button and a back space/erase key!) - I just received and used this calculator, and it's a steal. It replaces a much pricier HP 12C Platinum Calculator , which I'd gotten about five years ago when I needed the more advanced functions. I'd bought two of the HP 12C's, to have one as backup, and they were nothing like the 12Cs of before -- the keys malfunctioned on both of the 12Cs within just 25-50 uses (sticking and more often, not registering at all) and there was no easy fix. I've been tolerating them for the last few years, assuming that was just how calculators were made these days, but finally had enough. I just need basic calculator functions now, and for that, the Casio MS-80B is perfect. The interface is incredibly user friendly, the keys work flawlessly (so far), the display is large and clear, and the solar power is a bonus. I also wanted to clear up several question re: the MS-80B's keypad functions. This model does indeed have both an 'off' key and a delete/backspace key, which prior reviews said this calculator doesn't have. The picture currently displayed on desertcart's official product page (as of this review, 6/21/15) is wrong and shows model MS-80S, which lacks these two functions. It's possible that prior reviewers got the wrong model (?). The MS-80B has both an off key and a delete/backspace key, which sit on the top row of the keypad. The backspace key looks like a right-pointing arrow. I've attached a photo of the MS-80B so you can see for yourself. In sum, this is a great basic calculator, for an amazing price. I did a quick search of the other basic models available on desertcart, and this appears to be the best in terms of value, build, and reviews. I can't speak to its long-term durability, but for this price, I don't think you can go wrong! 4/7/16 UPDATE: This calculator is used at least weekly and is still going strong. I especially love the large buttons and display, and the solar power. I highly recommend this calculator for anyone who doesn't need advanced functions - from a quality perspective, it easily outperforms my high-end financial HPs (the HPs look more premier, but as I mentioned previously, the models as currently made fail quickly).

## Questions & Answers

**Q: When i use the percentage button, it calculates at a false rate. 100+10%=111.11111 that's what the calculator tells me. how do i fix this?**
A: I also was confused when trying to subtract percentages using the % key. I have never had a calculator function like this and I have had several other Casio models. Can confirm (X x Y% +/-) will get you the correct total "10 x 10% -" will get you 9 as an answer just as "10 x 10% +" will get you 11. Annoying to have to take an extra step, whatever Casio I'm sure you have your reasons.

**Q: On this calculator 50-10%=400 and 50+10%=55.55.  What am I doing wrong?**
A: To add or subtract a % from a number, using the % key, you first have to multiply the number by the %, then press + or –. Examples: To calculate 50 plus 10%, enter 50 x 10% (answer 5), then press + (answer 55). To calculate 50 minus 10%, enter 50 x 10% (answer 5), then press – (answer 45).

**Q: does it have a back button**
A: yES, IT DOES
Yes, it does.  The BACKSPACE (ERROR CORRECTION) KEY you're looking for is the ARROW directly to the left of the TAX- key.  Each press erases the last entered digit so it can then be reentered correctly.

**Q: Is this completely flat or is it curved at the top?**
A: The display window is curved at about a 25 degree angle for ea\asy reading.

### ⭐⭐⭐⭐⭐ The perfect everyday finger operated calculator!
*by C***E on February 17, 2016*

I make frequent use of a "real" calculator when working at my desk. I don't like the computer calculators which require mouse movement and clicking. I like to use my fingers. I had several calculators around the house (admittedly old ones, but serviceable) but given the lighting conditions in my office the screens were either too dim to show the LED numbers, or I had to tilt the screen to see the numbers, so I finally asked myself "why are you doing this - get a new one!" So I did. I wanted something where the screen was large, easy to read, and already tilted. This one fit my needs exactly. The numbers are very large and legible in even bright light. I really don't need to do advanced math, but I do a lot of percentage calculations, and maybe it's just me, but I could never get the "%" key to give me the percentage the way I wanted to see it. If I want to know (e.g.) what percent of 100 a value of 20 is, I want to divide 20 by 100 and push ONE key and see "20" as the percent. With this calculator, it has a "set %" key which displays exactly that - the number 20 as the percent value. It also has keys for easily adding tax to any value (you can set the tax percent then perform multiple calculations based on that initial tax % setting). And of course it does all the other normal calculator functions. So if you need just a straightforward calculator, and don't need it to have specialized features to do things like easily compute mortgage payments, etc. then this one fits the bill perfectly. Auto shutoff after a reasonable time, solar powered with battery, and above all easy to read!!
