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)$
