# How do you multiply the matrices ((1, 2), (3, 4)) with ((5, 6, 7), (8, 9, 10))?

$\left(\begin{matrix}1 & 2 \\ 3 & 4\end{matrix}\right) \times \left(\begin{matrix}5 & 6 & 7 \\ 8 & 9 & 10\end{matrix}\right)$
$\textcolor{w h i t e}{\text{XXX}} = \left(\begin{matrix}1 \times 5 + 2 \times 8 & 1 \times 6 + 2 \times 9 & 1 \times 7 + 2 \times 10 \\ 3 \times 5 + 4 \times 8 & 3 \times 6 + 4 \times 9 & 3 \times 7 + 4 \times 10\end{matrix}\right)$
$\textcolor{w h i t e}{\text{XXX}} = \left(\begin{matrix}21 & 24 & 27 \\ 47 & 54 & 61\end{matrix}\right)$
