## 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.
