Answer 2

As we know that identity element is a number, which combined with another element using an operation leaves the element unchanged.

1) Identity Element of Addition

identity element of addition is 0.

For example: if 0 is added to a real number, then the answer will be the real number number itself.

7+0=7

[Same is the case in Subtraction]

2) Identity Element Of Multiplication

identity element of multiplication is 1.

For example: if 1 is multiplied to any real number, then the answer will be the real number itself.

9×1=9

It depends on the binary operation, which you have not specified in the question.

I hope it will help you.
