Model Applied Situations with Matrix Operations
-Adjust the contrast by changing the black to light grey and the light grey to black. Use matrix addition to accomplish this.
A)

\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { r r r } 2 & - 2 & 2 \\2 & - 2 & 2 \\- 2 & - 2 & - 2\end{array} \right] = \left[ \begin{array} { l l l } 3 & 1 & 3 \\3 & 1 & 3 \\1 & 1 & 1\end{array} \right]

\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { l l l } - 2 & - 2 & - 2 \\- 2 & - 2 & - 2 \\- 2 & - 2 & - 2\end{array} \right] = \left[ \begin{array} { l l l } 3 & 1 & 3 \\3 & 1 & 3 \\1 & 1 & 1\end{array} \right]

\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { r r r } 1 & - 1 & 1 \\1 & - 1 & 1 \\- 1 & - 1 & - 1\end{array} \right] = \left[ \begin{array} { l l l } 3 & 1 & 3 \\3 & 1 & 3 \\1 & 1 & 1\end{array} \right]

\left[ \begin{array} { l l l } 1 & 3 & 1 \\1 & 3 & 1 \\3 & 3 & 3\end{array} \right] + \left[ \begin{array} { l l l } 2 & 2 & 2 \\2 & 2 & 2 \\2 & 2 & 2\end{array} \right] = \left[ \begin{array} { l l l } 3 & 1 & 3 \\3 & 1 & 3 \\1 & 1 & 1\end{array} \right]
