Problem:
Multiply the scalar $\frac{13}{3}$ and the matrix
$\left(
\begin{array}{cccc}
 -10 & 7 & 3 & -6 \\
 -2 & -6 & -5 & -6 \\
 -3 & 8 & -5 & -2 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{cccc}
 -\frac{130}{3} & \frac{91}{3} & 13 & -26 \\
 -\frac{26}{3} & -26 & -\frac{65}{3} & -26 \\
 -13 & \frac{104}{3} & -\frac{65}{3} & -\frac{26}{3} \\
\end{array}
\right)$
