Answer 1

$$\begin{array}{l} \left( \begin{array}{cccc} 6 & 2 & -3 \\ 0 & -4 & 5 \end{array} \right) - \left( \begin{array}{ccc} 4 & -1 & 2 \\ -5 & 1 & -2 \end{array} \right) = \left( \begin{array}{ccc} 6 - 4 & 2 - (-1) & -3 - 2 \\ 0 - (-5) & -4 - (1) & 5 - (-2) \end{array} \right) \\ = \left( \begin{array}{ccc} 2 & 3 & -5 \\ 5 & -5 & 7 \end{array} \right) \\ \end{array}$$
