What is the additive inverse of -7?

Solution:

If a number is added to its additive inverse, the sum of both the numbers becomes zero.

For any given number, the additive inverse is a number or a value which when added to the original number results in zero.

Mathematically: a + (-a) = 0

So here, 'a' and '-a' are the additive inverses of each other.

Therefore, for -7, the additive inverse is 7 as (-7) + 7 = 0

Thus, 7 is the additive inverse of -7.
