Scalar and vector quantities: Flashcards

Complete the results of adding and subtracting these column vectors:

\begin{pmatrix} 2 \\ 1 \end{pmatrix} + \begin{pmatrix} 1 \\ 4 \end{pmatrix} = \begin{pmatrix} \_\_\_\_\_\_ \\ 5 \end{pmatrix} \text{ and } \begin{pmatrix} 2 \\ 1 \end{pmatrix} - \begin{pmatrix} 1 \\ 4 \end{pmatrix} = \begin{pmatrix} 1 \\ \_\_\_\_\_\_ \end{pmatrix}
