My game is based on PEMDAS which stands for parenthesis, exponent, multiply or divide, add or subtract. That is the order of operations that you have to solve math problems in. If there is a problem that has divide before subtract, you divide first in the order the problem goes in, if division is first you do that, if multiplication comes first then you multiply. It's the same thing with adding and subtracting, but with parenthesis and exponent you always go in the order of PEMDAS no matter where it shows up in the problem. I chose this subject because this is my best math skill. PEMDAS was complicated for me at first then it started getting easier.
