$2. \left[\begin{array}{ccc}0&4&-2\\6&2&8\\\end{array}\right] - \left[\begin{array}{ccc}-3&6&9\\12&-6&0\\\end{array}\right] + 3. \left[\begin{array}{ccc}0&-1&0\\1&-1&2\\\end{array}\right]$


{$\left[\begin{array}{ccc}0&8&-4\\12&4&16\\\end{array}\right] - \left[\begin{array}{ccc}-3&6&9\\12&-6&0\\\end{array}\right] + \left[\begin{array}{ccc}0&-3&0\\3&-3&6\\\end{array}\right]$

$\left[\begin{array}{ccc}3&2&-13\\0&10&16\\\end{array}\right] +\left[\begin{array}{ccc}0&-3&0\\3&-3&6\\\end{array}\right]$

$\left[\begin{array}{ccc}3&-1&-13\\3&7&22\\\end{array}\right]$
