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

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

Evaluate

$$\left(\begin{matrix}6\\5\\3\end{matrix}\right)$$

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.

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

To add two matrices, add the corresponding elements.

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

Sum each element of the matrix.

$$\left(\begin{matrix}6\\5\\3\end{matrix}\right)$$

Transpose Matrix

$$\left(\begin{matrix}6&5&3\end{matrix}\right)$$
