Calculator

Hesham0 (24)
I've managed to create a calculator that accepts different operators and any amount of numbers using arrays. However, it doesn't calculate the ( * and / ) before the ( + and - ) which I didn't manage to do. I'd like it to calculate the * and / first, any help would be appreciated.
