 Multiplicative inverse

A multiplicative inverse of $x$ is an element $x^{-1}$ satisfying $x{x}^{-1}=x^{-1}x=1$.

The multiplicative inverse of a number \( x \) is another number, often denoted as \( \frac{1}{x} \) or \( x^{-1} \), such that when you multiply the two numbers together, the result is 1.
