Question

Write the negative (additive inverse) of each of the following:

vii) $-1$

Answer 1

We know that,
The negative or additive inverse of rational number
$\frac{a}{b}\text{is}-\frac{a}{b}$ such that $\frac{a}{b}+(-\frac{a}{b})=0$

$\therefore \text{Negative of}-1=-(-1)$
$=1$

Hence, the additive inverse of $-1$ is $1$.
