Problem:
Multiply
$\left(
\begin{array}{cc}
 \frac{1}{2} & -1 \\
 \frac{5}{2} & -\frac{5}{2} \\
\end{array}
\right)$ and
$\left(
\begin{array}{ccccc}
 -\frac{3}{2} & \frac{5}{2} & \frac{1}{2} & \frac{1}{2} & 3 \\
 -\frac{3}{2} & -3 & -3 & \frac{3}{2} & -\frac{3}{2} \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{ccccc}
 \frac{3}{4} & \frac{17}{4} & \frac{13}{4} & -\frac{5}{4} & 3 \\
 0 & \frac{55}{4} & \frac{35}{4} & -\frac{5}{2} & \frac{45}{4} \\
\end{array}
\right)$
