Solve {l}{1}{2}{3}+{l}{4}{5}{6}

$$\left( \begin{array} { l } { 1 } \\ { 2 } \\ { 3 } \end{array} \right) + \left( \begin{array} { l } { 4 } \\ { 5 } \\ { 6 } \end{array} \right)$$

Evaluate

$$\left(\begin{matrix}5\\7\\9\end{matrix}\right)$$

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.

$$\left(\begin{matrix}1\\2\\3\end{matrix}\right)+\left(\begin{matrix}4\\5\\6\end{matrix}\right)$$

To add two matrices, add the corresponding elements.

$$\left(\begin{matrix}1+4\\2+5\\3+6\end{matrix}\right)$$

Sum each element of the matrix.

$$\left(\begin{matrix}5\\7\\9\end{matrix}\right)$$

Transpose Matrix

$$\left(\begin{matrix}5&7&9\end{matrix}\right)$$
