Which equation demonstrates the multiplicative identity property

The multiplicative identity property is one of the four properties of multiplication (besides commutative, associative and distributive). It states that any time you multiply a number by 1, the result, or product, is that original number.

The equation that demonstrates this identity property is:

A*1 = A, where A is any number

or 1*A=A

A*1=A=1*A
