(mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; the multiplicative inverse of 7 is 1/7

Two numbers are multiplicative inverses of each other if their product is 1 (e.g., since 4 x 1/4 = 1, 1/4 and 4 are multiplicative inverses).

Pairs of real numbers that have the product 1.

any two numbers with a product of 1 (e.g., 4 and 1/4).

The reciprocal of a number. Any number multiplied by its multiplicative inverse equals 1.

The reciprocal of a number; the number, which when multiplied by a given number, produces the multiplicative identity 1; in the set of real numbers the number a given number needs to be multiplied by to yield 1.; n*n-inverse = 1 for all n. Examples: 7x1/7=1 and 2/3 * 3/2 = 1.

In mathematics, the reciprocal, or multiplicative inverse, of a number x is the number which, when multiplied by x, yields . The multiplicative inverse for the real numbers, for example, is 1/x. To avoid confusion by writing the inverse using set specific notation, we generally write x-1.
