Solve {l}{1}{2}+{l}{3}{4}=

$$\left( \begin{array} { l } { 1 } \\ { 2 } \end{array} \right) + \left( \begin{array} { l } { 3 } \\ { 4 } \end{array} \right) =$$

Evaluate

$$\left(\begin{matrix}4\\6\end{matrix}\right)$$

Steps Using Rules for Matrix Arithmetic

You can add or subtract two matrices only if both matrices have the same number of rows and columns.

$$\left(\begin{matrix}1\\2\end{matrix}\right)+\left(\begin{matrix}3\\4\end{matrix}\right)$$

To add two matrices, add the corresponding elements.

$$\left(\begin{matrix}1+3\\2+4\end{matrix}\right)$$

Add 1 to 3.

$$\left(\begin{matrix}4\\2+4\end{matrix}\right)$$

Add 2 to 4.

$$\left(\begin{matrix}4\\6\end{matrix}\right)$$

Transpose Matrix

$$\left(\begin{matrix}4&6\end{matrix}\right)$$
