Question

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 .


This his is the answer I got for the question I asked , I am not able to understand the answer.

Answer 1

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number),[1] sign change, and negation.[2] For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive. Zero is the additive inverse of itself.

The additive inverse of a is denoted by unary minus: −a (see the discussion below). For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0
