If $\mathbf{A}=\left(\begin{array}{ll}a & b \\ c & d\end{array}\right)$ and $\mathbf{B}=\left(\begin{array}{ll}2 & 1 \\ 3 & 2\end{array}\right)$, find $\mathbf{A}$ such that $\mathbf{A} \mathbf{B}=\left(\begin{array}{ll}3 & 2 \\ 1 & 4\end{array}\right)$
If $A=\left[\begin{array}{cc}1 & 2 \\ -1 & 0 \\ 1 & -3\end{array}\right], B=\left[\begin{array}{cc}4 & 5 \\ -1 & 0 \\ 2 & 1\end{array}\right], C=\left[\begin{array}{cc}-1 & -2 \\ -1 & 2 \\ -1 & -2\end{array}\right]$, find $A-2 B+3 C$.
Given $A=\left[\begin{array}{rrr}1 & -2 & 3 \\ 4 & 5 & -6\end{array}\right]$ and $B=\left[\begin{array}{rrr}3 & 0 & 2 \\ -7 & 1 & 8\end{array}\right],$ find: (a) $A+B,$ (b) $2 A-3 B.$
