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. ## 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.ro/products/1144754-casio-ms-80b-desktop-calculator-tax-and-currency-tools](https://www.desertcart.ro/products/1144754-casio-ms-80b-desktop-calculator-tax-and-currency-tools) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-05*
