Hint: Additive inverse of the number is stated as the number whose addition with the given number yields zero as a result. So the additive inverse of x is (-x) and sum of both the number is $0$

Given $( - 3)$
Let additive inverse of $( - 3)$be x
$\Rightarrow x + ( - 3) = 0 \\ \Rightarrow x = 3 \\$
So the additive inverse of $( - 3)$is 3.
The additive inverse of x is equal and opposite in sign to it (so, y = -x or vice versa). For example, the additive inverse of the positive number $5$ is $- 5$.
