Problem:
Add the two matrices
$\left(
\begin{array}{cccc}
 -9 & -\frac{29}{8} & \frac{19}{2} & \frac{21}{4} \\
 \frac{1}{8} & -\frac{3}{8} & 0 & \frac{25}{4} \\
\end{array}
\right)$ and
$\left(
\begin{array}{cccc}
 -\frac{37}{4} & \frac{11}{2} & \frac{47}{8} & \frac{11}{4} \\
 -\frac{5}{4} & \frac{21}{4} & \frac{79}{8} & \frac{63}{8} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{cccc}
 -\frac{73}{4} & \frac{15}{8} & \frac{123}{8} & 8 \\
 -\frac{9}{8} & \frac{39}{8} & \frac{79}{8} & \frac{113}{8} \\
\end{array}
\right)$
