USE BASIC MATLAB CODE IF POSSIBLE $*****$

Three matrices are defined as

$A=\left[\begin{array}{cc}6& -1\\ 12& 7\\ -5& 2\end{array}\right],B=\left[\begin{array}{cc}4& 0\\ 1& 8\end{array}\right],C=\left[\begin{array}{cc}1& -2\\ -6& 1\end{array}\right]$

$($a$)$ Perform by hand all possible multiplications that can be computed between pairs of these

matrices.

$($b$)$ Justify why the remaining pairs cannot be multiplied.

$($c$)$ Use the results of $($a$)$ to illustrate why the order of multiplication is important.
