Just listen to the calculator. Use only numbers (123, not one two three) or it won't work. For the operations: + for addition, - for subtraction, * or x for multiplication, e for exponents and finally / for division.
This only does addition, subtraction, multiplication, exponents and division. Could you change it to add more operations? You could also change the graphics or even incorporate a game into it! Thanks to my friend GillyTheGillerDog77 for the idea with his project Epiccalculator! Updates: v1.6 brings: -Fixed the exponents to tell the correct answer on exponents above three v1.5 brings: -Added the Exponent operation. Num1 is base, Num2 is exponent. Sorta Confusing. v1.0 brings: -The project, of course!
