\[ \begin{array} {ccccc} \large & & & \color{green}A & \color{green}A & \color{green}A\\ \large \times & & & & \color{red}B & \color{purple}C \\ \hline \large & \color{green}A & 0 & \color{green}A & 0 & \color{green}A \end{array} \]
\[ \begin{array} {ccc} \large & & \color{green}A & \color{green}A\\ \large + & & \color{purple}C & \color{green}A \\ \hline \large & & \color{red}B & \color{blue}D \end{array} \]
