Question

Subtract the following.

$\left(-8\right)$ from $\left(-7\right)$

Answer 1

Subtract the numbers:

We have, $\left(-7\right)-\left(-8\right)$

Now, the additive inverse of $\left(-8\right)$ is $+8$.

Add the additive inverse to $\left(-7\right)$.

We get,

$$\begin{gathered} \left(-7\right)-\left(-8\right)=-7+8 \\ =1 \end{gathered}$$

Hence, $\left(-7\right)-\left(-8\right)=1$.
