# Vector Addition

Two vectors of the same size can be added together by adding their corresponding elements, to form another vector of the same size, called the sum of the vectors. \[ \begin{bmatrix} 0 \\ 7 \\ 3 \end{bmatrix} + \begin{bmatrix} 1 \\ 2 \\ 0 \end{bmatrix} = \begin{bmatrix} 1 \\ 9 \\ 3 \end{bmatrix} \] Likewise, for substraction, the difference of two vectors is \[ \begin{bmatrix} 1 \\ 9 \end{bmatrix} - \begin{bmatrix} 1 \\ 1 \end{bmatrix} = \begin{bmatrix} 0 \\ 8 \end{bmatrix} \] …
