Question

Add the matrices: $open square brackets table row cell negative 2 end cell row 4 end table close square brackets comma space open square brackets table row 3 row cell negative 2 end cell end table close square brackets$

$[\begin{array}{l} 1 \\ 3 \end{array}]$
$[\begin{array}{l} 1 \\ 2 \end{array}]$
$[\begin{array}{l} 1 \\ 6 \end{array}]$
$[\begin{array}{l} 5 \\ 6 \end{array}]$

hint Hint:

Two or more matrices of the same order can be added by adding the corresponding elements of the matrices.
If A = [aij] and B = [bij] are two matrices with the same dimension, that is, they have the same number of rows and columns, then the addition of matrices A and B is: A+B = [aij] + [bij] = [aij + bij], where ij denotes the position of each element in i^th row and j^th column.

The correct answer is: $open square brackets table attributes columnalign left end attributes row 1 row 2 end table close square brackets$

Two or more matrices of the same order can be added by adding the corresponding elements of the matrices.
$A space equals space open square brackets table row cell negative 2 end cell row 4 end table close square brackets comma B space equals space open square brackets table row 3 row cell negative 2 end cell end table close square brackets A space plus space B space equals space open square brackets table row cell negative 2 end cell row 4 end table close square brackets space plus space open square brackets table row 3 row cell negative 2 end cell end table close square brackets A space plus space B space equals space open square brackets table row cell negative 2 space plus space 3 end cell row cell 4 space plus space minus 2 end cell end table close square brackets space equals space open square brackets table row 1 row 2 end table close square brackets$
