Compute the following sums: `[[3,-2],[ 1, 4]]+[[-2, 4],[ 1 ,3]]`

Explanation

$${\left[\begin{array}{rr}3 & -2 \\ 1 & 4\end{array}\right]+\left[\begin{array}{cc}-2 & 4 \\ 1 & 3\end{array}\right] }$$
$$\Rightarrow\left[\begin{array}{lr}3-2 & -2+4 \\ 1+1 & 4+3\end{array}\right]$$
$$\Rightarrow\left[\begin{array}{ll}1 & 2 \\ 2 & 7\end{array}\right]$$
