Multiplicative inverse
In mathematics, a multiplicative inverse or reciprocal for a nonzero number x, denoted by 1 x {\displaystyle {\tfrac {1}{x}}} or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a b {\displaystyle {\tfrac {a}{b}}} is b a . {\displaystyle {\tfrac {b}{a}}.} Dividing 1 by a real number yields its multiplicative inverse. 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. The reciprocal function, the function f(x) that maps x to...
