Solution

Explanation:

Additive Inverse: An additive inverse of a number is another number, which gives zero, when added to the original number.

For example: If 2 is the original number then -2 will be its additive inverse as 2+(-2)=0

Therefore, we can say that (-a) is the Additive inverse of a as a+(-a)=0

Hence, to get additive inverse of an integer a,we have to multiply it by -1,

As, a×(-1)=-a

Hence, -1 is the answer.
