Question

Subtract the following.

$\left(-6\right)$ from $\left(-7\right)$

Answer 1

We have, $\left(-7\right)-\left(-6\right)$

Now, the additive inverse of $\left(-6\right)$ is $+6$.

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

We get,

$$\begin{gathered} \left(-7\right)-\left(-6\right)=-7+6 \\ =-1 \end{gathered}$$

Hence, $\left(-7\right)-\left(-6\right)=-1$
