Answer:
0
Step-by-step explanation:
Given the value of a variable x, the additive inversee will be its negative value.
Hence the additive inverse of x is -x
For a value of 4, then its additive inverse is -4
Taking the sum of 4 and its additive inverse, we will have;
= 4 + (-4)
= 4 - 4
= 0
Hence the sum of 4 and its additive inverse is 0
