For this case we have to, to add matrices, we must add term to term, that is:

Let:

$C=\left[\begin{array}{cc}a&b\\c&d\\\end{array}\right]$ and
$D=\left[\begin{array}{cc}e&f\\g&h\\\end{array}\right]$

We have to:

$C+D=\left[\begin{array}{cc}a+e&b+f\\c+g&d+h\\\end{array}\right]$

Then, solving the given exercise we have:

$A+B=\left[\begin{array}{cccc}3+2&0+8&0+6&-1+3\\\end{array}\right]$

Taking into account that different signs are retsn and the sign of the major is placed, we have:

$A+B=\left[\begin{array}{cccc}5&10&6&2\\\end{array}\right]$

Thus,
$A+B=\left[\begin{array}{cccc}5&10&6&2\\\end{array}\right]$

Answer:

$A+B=\left[\begin{array}{cccc}5&10&6&2\\\end{array}\right]$
