Solve {l}{342}{571}{982}+{l}{479}{122}{456}

$$\left( \begin{array} { l } { 342 } \\ { 571 } \\ { 982 } \end{array} \right) + \left( \begin{array} { l } { 479 } \\ { 122 } \\ { 456 } \end{array} \right)$$

Evaluate

$$\left(\begin{matrix}821\\693\\1438\end{matrix}\right)$$

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.

$$\left(\begin{matrix}342\\571\\982\end{matrix}\right)+\left(\begin{matrix}479\\122\\456\end{matrix}\right)$$

To add two matrices, add the corresponding elements.

$$\left(\begin{matrix}342+479\\571+122\\982+456\end{matrix}\right)$$

Sum each element of the matrix.

$$\left(\begin{matrix}821\\693\\1438\end{matrix}\right)$$

Transpose Matrix

$$\left(\begin{matrix}821&693&1438\end{matrix}\right)$$
