Problem:
Add the two matrices
$\left(
\begin{array}{c}
 \frac{21}{5} \\
 -\frac{59}{10} \\
 \frac{6}{5} \\
 -\frac{19}{10} \\
\end{array}
\right)$ and
$\left(
\begin{array}{c}
 \frac{79}{10} \\
 \frac{51}{10} \\
 -\frac{49}{10} \\
 -\frac{7}{5} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{c}
 \frac{121}{10} \\
 -\frac{4}{5} \\
 -\frac{37}{10} \\
 -\frac{33}{10} \\
\end{array}
\right)$
