Question

For any integer $a$, its additive inverse is ..........

• A. $-a$
• B. $a$
• C. $\frac{1}{a}$
• D. $\frac{-1}{a}$

Answer 1

The correct option is A $-a$

The additive inverse of a number $a$ is the number that, when added to $a$ yields zero.

This number is also known as the negative, or negation.

If $a$ is an integer, then its negative or additive inverse is $(-a)$
