Definition of Multiplicative Inverse

Definition of Multiplicative Inverse

Every real number, except for zero, has a multiplicative inverse. The multiplicative inverse of \(x\) is the number you multiply \(x\) by to get the multiplicative identity \(1\) as the product.

The multiplicative inverse for a number \(x \neq 0\) is equal to the reciprocal of \(x\):

\( x \times \dfrac{1}{x} = \dfrac{1}{x} \times x = 1. \)

For example, the multiplicative inverse of \(7\) is \(\dfrac{1}{7}\), and the multiplicative inverse of \(-3\) is \(\dfrac{1}{-3}\).

So, the multiplicative inverse of an elephant is shown in the picture to the left. Elephants are real, aren't they?
