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?

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.

On this calculator 50-10%=400 and 50+10%=55.55. What am I doing wrong?

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).

does it have a back button

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.

Is this completely flat or is it curved at the top?

The display window is curved at about a 25 degree angle for ea\asy reading.
