Question

Find the additive inverse of the number

$3$

Answer 1

Additive inverse: An additive inverse of a number is defined as the value, which on adding with the original number results in zero value.

Suppose, $a$ is the original number, then its additive inverse will be minus of $a$ i.e., $-a$, such that;

$a+(-a)=a–a=0$

Here, $a=3$, then$-a=-\left(3\right)=-3$, so that,

$3-3=0$

Hence, the additive inverse of $3$ is $-3$.
