Question

What is multiplicative identity?

Answer 1

Multiplicative identity:

The multiplicative identity is applied while performing the operation of multiplication. Multiplicative identity states that if a number is multiplied to $1$ the resultant will be the number itself.

So, “$1$” is the multiplicative identity of a number.

It is represented as $a\times 1=a=1\times a$.

Example:

$5\times 1=5=1\times 5$
