Answer
The solution for the indicated problem is $8$.
Work Step by Step
Solve the given expression:
Recall that $-\left( -a \right)=a$
$\begin{align}
& \frac{1}{2}\left[ 8-\left( -8 \right) \right]=\frac{1}{2}\left[ 8+8 \right] \\
& =\frac{1}{2}\left[ 16 \right] \\
& =8
\end{align}$
Hence, the solution for the indicated problem is $8$.
