Answer
\[
MN=
\left[ {\begin{array}{cc}
OW+IY&OX+IZ\\
IW+OY&IX+OZ
\end{array} } \right]
\]
Work Step by Step
The product of \[
M=
\left[ {\begin{array}{cc}
0&I \\
I&O
\end{array} } \right]
\]
and
\[
N=
\left[ {\begin{array}{cc}
W&X\\
Y&Z
\end{array} } \right]
\]
is
\[
MN=
\left[ {\begin{array}{cc}
OW+IY&OX+IZ\\
IW+OY&IX+OZ
\end{array} } \right]
\]
