Question

what is additive identity for integer?

Answer 1

if a is an integer it's additive identity = -a

a+(-a) =0

-a+a=0(a is additive inverse of -a)

example:

5 is additive inverse of -5

-5 is additive inverse of 5

Answer 2

Additive identity of an integer is such a property in which the sum of a given integer & 0 must be same given number.

Example: Find the additive identity of -5 & 7.
Solution:
Given number = -5
Additive identity of -5 = -5+0 = -5
Hence additive identity of -5 is 0.

Given number = 7
Additive identity of 7 = 7 +0 =7
Hence, additive identity of 7 is 0

We conclude from these examples that identity if an integer either negative or positive altogather 0 is 0.
