WELCOME TO MY CALCULATOR!!! Type the first number in your equation, then the second. Then Type either Add Subtract Multiply or Divide (you have to make the first letter a capital letter or it won't work) - NO FRACTIONS - NO DECIMALS - NO PERCENTAGES - NO LETTERS -
Notes: This is a work in progress, I'm still working on it so yeah. So far you can only use numbers 1 to 20 If the answer is 1 to 20 then it will show up on the calculator screen, if not, then it just shows up as a variable.
