Answer 1

$t_A=\left[\begin{array}{ccc}6&3\\-2&-1\\\end{array}\right] \end{array}\right] \\t_B=\left[\begin{array}{ccc}-1&2\\-4&1\\\end{array}\right] \end{array}\right] \\A+B=\left[\begin{array}{ccc}6-1&-2-4\\3+2&-1+1\\\end{array}\right] \end{array}\right] \\t_a+t_b=\left[\begin{array}{ccc}6-1&3+2\\-2-4&-1+1\\\end{array}\right] \\\end{array}\right] \\B-A=\left[\begin{array}{ccc}-1-6&-4-2\\2-3&1-1\\\end{array}\right] \end{array}\right]$

$t_B-t_A=\left[\begin{array}{ccc}-1-6&2-3\\-4-2&1+1\\\end{array}\right] \end{array}\right]$
