## in·verse

(ĭn-vûrs′)*Adjective*

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*(ĭn′vûrs′)

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

**2.**Either of two numbers or quantities that cancel each other out under a given mathematical operation. For example, the inverse of 5 under multiplication is

^{1}/

_{5}, since 5 ×

^{1}/

_{5}= 1. The inverse of 5 under addition is -5, since 5 + -5 = 0.
