For adding matrices, their dimension should be equal.

First write the dimension of the matrix.

The dimensions of matrix A and B are $\"\"$ .

The operation A + B is possible. $\"\"$

Add the matrix A + B \ \

$\"\"$ (Substitute the values of A and B)

$\"\"$ (Add corresponding elements)

$\"\"$ (Simplify) $\"\"$

The value of A + B is $\"\"$ .
