Programmed Math/Subtraction< Programmed Math
Subtraction deals with the taking away of numbers, like number a from number b so that: a >= b while b > a. Such a case is with:
a = 36 and b = 5.
So a - b = 36-５ = 31, a >= b is true, and b > a is initially true.
Subtraction is the inverse of addition, meaning that it is the opposite.
