A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Given are the following matrices:

\begin{displaymath}A=
\left(
\begin{array}{cc}
1 & -2\\
-2 & 4
\end{array}...
...\left(
\begin{array}{ccc}
1 & 7 & -1
\end{array}
\right)
,\end{displaymath}

\begin{displaymath}D=
\left(
\begin{array}{c}
4 \\
5 \\
6
\end{array}
\...
...4\\
-1 & 0 & 0 & 4\\
5 & 7 & 3 & 1
\end{array}
\right)
\end{displaymath}


Calculate the following products:


$ AB= \left(\rule{0pt}{5ex}\right.$
$ \left.\rule{0pt}{5ex}\right)$ , $ BA= \left(\rule{0pt}{5ex}\right.$
$ \left.\rule{0pt}{5ex}\right)$ , $ CD= \left(\rule{0pt}{2ex}\right.$
$ \left.\rule{0pt}{2ex}\right)$
,

$ DC= \left(\rule{0pt}{7ex}\right.$
$ \left.\rule{0pt}{7ex}\right)$ , $ EF= \left(\rule{0pt}{7ex}\right.$
$ \left.\rule{0pt}{7ex}\right)$ , $ EE= \left(\rule{0pt}{7ex}\right.$
$ \left.\rule{0pt}{7ex}\right)$
