Problem Statement
Ahmed and his friend, Omar, were studying for their math exam at a coffee shop in Amman, Jordan. They both had calculators with them, but they realized that they couldn't perform simple calculations on each other's devices due to different operating systems. Ahmed asked Omar to help him write a small program that would take two numbers as input and output the sum, difference, product, and quotient of those numbers. This way, they could quickly calculate any mathematical expression without needing an actual calculator.
