[tex]3 \left[\begin{array}{ccc}2&1\\0&-3\end{array}\right] = \left[\begin{array}{ccc}6&3\\0&-9\end{array}\right] \\ \\ - 2\left[\begin{array}{ccc}-1&3\\4&2\end{array}\right] = \left[\begin{array}{ccc}2&-6\\-8&-4\end{array}\right] \\ \\ \left[\begin{array}{ccc}6&3\\0&-9\end{array}\right] + \left[\begin{array}{ccc}1&1\\0&2\end{array}\right] = \left[\begin{array}{ccc}7&4\\0&-7\end{array}\right] \\ \\ [/tex]

[tex]\left[\begin{array}{ccc}7&4\\0&-7\end{array}\right] + \left[\begin{array}{ccc}2&-6\\-8&-4\end{array}\right] = \left[\begin{array}{ccc}9&-2\\-8&-11\end{array}\right][/tex]
