Solution

$A = ⎡ ⎢ ⎣ \begin{matrix} - 1 & 0 & 2 2 & 3 & 4 0 & 1 & 2 \end{matrix} ⎤ ⎥ ⎦ B = ⎡ ⎢ ⎣ \begin{matrix} 2 & 2 & - 4 - 4 & 2 & - 4 2 & - 1 & 5 \end{matrix} ⎤ ⎥ ⎦$
$A + B = ⎡ ⎢ ⎣ \begin{matrix} - 1 & 0 & 2 2 & 3 & 4 0 & 1 & 2 \end{matrix} ⎤ ⎥ ⎦ + ⎡ ⎢ ⎣ \begin{matrix} 2 & 2 & - 4 - 4 & 2 & - 4 2 & - 1 & 5 \end{matrix} ⎤ ⎥ ⎦$
$A + B = ⎡ ⎢ ⎣ \begin{matrix} 1 & 0 & - 2 - 2 & 5 & 0 2 & 0 & 7 \end{matrix} ⎤ ⎥ ⎦$
