Question

Which expression is the additive inverse of n?

A. 1/n
B. -n
C. -1/n
D. -(-n)

Answer 1

The additive inverse of n is -n.

Step-by-step explanation:

The additive inverse of a number n is the number that when added to n gives a sum of zero. In this case, the correct expression that represents the additive inverse of n is -n which is option B.

For example, if n = 5, then the additive inverse of 5 is -5 because 5 + (-5) = 0. Similarly, if n = -3, then the additive inverse of -3 is 3 because -3 + 3 = 0.

Options A, C, and D are not additive inverses of n.

Answer 2

The additive inverse of something is whats added to the original to get 0

So in this case n - n = 0, which is B :)
