Given $A=\left[\begin{array}{ll}1 & 0\end{array}\right]$ and $B=\left[\begin{array}{l}0 \\ 1\end{array}\right]$, find $A B$ and $B A$.
If $A=\left[\begin{array}{ll}1 & 1 \\ 0 & 1\end{array}\right], B=\left[\begin{array}{ll}0 & 1 \\ 1 & 0\end{array}\right]$, then find $A B$ and $B A$ and show that $A B \neq B A$.
If $A=\left[\begin{array}{ll}a & b \\ c & d\end{array}\right]$ and $B=\left[\begin{array}{rr}1 & 1 \\ -1 & 1\end{array}\right]$, find $a, b, c, d$ so that $A B=B A$.
