Only use a variable when you need to refer to it later
e.g., Not x = 100, print(x). Just print(100)

- you can check whether one number is divisible by another—if x % y is zero, then x is divisible by y. This can be used, in particular, to determine whether an integer is even or odd. If x % 2 is zero, then x is even. If x % 2 is 1, then x is odd.
- You can also use % to extract the right-most digit or digits from a number. For example, x % 10 yields the right-most digit of x (in base 10). Similarly x % 100 yields the last two digits.
