In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x â1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a.For the multiplicative inverse of a real number, divide 1 by the number.For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.he notation f â1 is sometimes also used for the inverse function of the function f, which is not in general equal to the multiplicative inverse. For example, the multiplicative inverse 1/(sin x) = (sin x)â1 is different from the inverse sin of x, denoted sinâ1 x or arcsin x.
In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa.
