An inverse operation. Subtraction is the inverse of addition.
Either of a pair of elements in a set whose result under the mathematical operation of the set is the identity element. For example, the inverse of 5 under multiplication is 1/5 , since 5 × 1/5 = 1, the identity element under multiplication. The inverse of 5 under addition is -5, since 5 + -5 = 0.
