Problem:
Add the two matrices
$\left(
\begin{array}{ccc}
 -\frac{119}{20} & \frac{144}{25} & -\frac{489}{50} \\
 \frac{927}{100} & \frac{174}{25} & -\frac{879}{100} \\
\end{array}
\right)$ and
$\left(
\begin{array}{ccc}
 \frac{81}{50} & \frac{443}{50} & \frac{303}{100} \\
 \frac{323}{50} & -\frac{127}{50} & -\frac{557}{100} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{ccc}
 -\frac{433}{100} & \frac{731}{50} & -\frac{27}{4} \\
 \frac{1573}{100} & \frac{221}{50} & -\frac{359}{25} \\
\end{array}
\right)$
