Q. How to do additive inverse ?
Answer: in mathematics, inverse of an operation is said to be an number/unit such that if that number is operated on another number the same number is obtained back .
in addition the number is 0 .
This is because whenever we add any number with 0 we get the original number.
For example :-
2+0 =2
3+0=3
17+0=0
100+0=0
and so on .

The property of an an addition is called as additive inverse .
