Question

operation will not change the value of any non zero number

​

Answer 1

By multiplying with "1"

Explanation:

The question is incomplete.

The complete question is "which operation will not change the value of any non zero number"

So, we know that multiplying any non zero number by "1" will not change the value of the number that is why it is also known as multiplicative identity. Such as

11 x 1 = 11

50 x 1 = 50

100 x 1 = 100

Any number multiplied by "1" is the same number
