Multiplicative inverse: The multiplicative inverse

The multiplicative inverse , or reciprocal, of a number is a value that, when multiplied with the original number, results in a product of one. It is also called the reciprocal of a number. Learn what multiplicative inverse is and how to find it for different types of numbers. Explore the multiplicative inverse property, fun facts, and practice problems with solutions. Multiplicative inverse of a number is another number that, when multiplied by the original number, results in the identity element for multiplication , which is 1. In other words, for a non-zero number a, its multiplicative inverse is denoted as a−1, and it satisfies the equation: a⋅a-1 = 1.
