Learning about Subtraction

Subtraction is an operation in which one number is taken away from another number. For example, 4 – 1 = 3 (four minus one equals three). A number minus itself is equal to zero (for example, 3 – 3 = 0). Subtraction is the inverse operation of addition. That is, a + b – b = a. Subtraction is considered to be a binary operation because it is performed on two numbers.
