inverse

1. Relating to a mathematical operation whose nature or effect is the opposite of another operation. For example, addition and subtraction are inverse operations, as are multiplication and division.

Noun

1. An inverse operation. Subtraction is the inverse of addition.
2. 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.
