[tex] R = \left[\begin{array}{ccc}-2&6&7\\-1&-8&9\end{array}\right] \\ \\ R^{t} = \left[\begin{array}{ccc}-2&-1\\6&-8\\7&9\end{array}\right] \\ \\ S = \left[\begin{array}{ccc}4&-3&10\\-2&7&11\end{array}\right] \\ \\ S^{t} = \left[\begin{array}{ccc}4&-2\\-3&7\\10&11\end{array}\right] \\ \\ \\ \\ a. \left[\begin{array}{ccc}-2&-1\\6&-8\\7&9\end{array}\right] + \left[\begin{array}{ccc}4&-2\\-3&7\\10&11\end{array}\right] = \left[\begin{array}{ccc}2&-3\\3&-1\\17&20\end{array}\right][/tex]

[tex] b. 2\left[\begin{array}{ccc}-2&6&7\\-1&-8&9\end{array}\right] - \left[\begin{array}{ccc}4&-3&10\\-2&7&11\end{array}\right] = \\ \\ \left[\begin{array}{ccc}-4&12&14\\-2&-16&18\end{array}\right] - \left[\begin{array}{ccc}4&-3&10\\-2&7&11\end{array}\right] = \left[\begin{array}{ccc}-8&15&4\\0&-23&7\end{array}\right] [/tex]
