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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ An inexpensive, easy to read, solar powered calculator *by J***D on July 23, 2026* Good household calculators are always useful.

They work great, they last a long time. It is very convenient that you don't need batteries because it is solar-powered, which it's a plus. Size is good and the numbers are very bright. I totally recommend it. ### ⭐⭐⭐⭐⭐ Best inexpensive calculator *by A***R on September 16, 2025* 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. ## Frequently Bought Together - Casio MS-80B Calculator – Desktop Calculator with Tax & Currency Tools | General Purpose | Large Display | Ideal for Home, Office & Everyday Math - Amazon Basics Stapler with 1000 Staples, Office Stapler, 25 Sheet Capacity, Non-Slip, Black - Scotch Classic Desktop Tape Dispenser, Black, 1-inch Core, Made from 100% Recycled Plastic, 1 Dispenser --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/1144754-ms-80b-desktop-calculator-tax-and-currency-tools](https://www.desertcart.sk/products/1144754-ms-80b-desktop-calculator-tax-and-currency-tools) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-20*
