If $A = \left[\begin{array}{cc} -4 &1\cr -4 &4 \end{array}\right]$ and $B = \left[\begin{array}{cc} 6 &-4\cr 3 &-1 \end{array}\right]$, then

$AB=$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$ and

$BA=$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$.

Choose True False True or False: $AB = BA$ for any two square matrices $A$ and $B$ of the same size.
