Problem:
Add the two matrices
$\left(
\begin{array}{c}
 9 \\
 -\frac{27}{8} \\
 -\frac{17}{8} \\
\end{array}
\right)$ and
$\left(
\begin{array}{c}
 -\frac{71}{8} \\
 \frac{9}{2} \\
 \frac{59}{8} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{c}
 \frac{1}{8} \\
 \frac{9}{8} \\
 \frac{21}{4} \\
\end{array}
\right)$
