$\vec{A B} = \vec{O B} - \vec{O A}$

$\vec{A B} + \vec{B C} = \vec{A C}$

\begin{aligned} \vec{A B} + \vec{B C} & = (\vec{O B} - \vec{O A}) + (\vec{O C} + \vec{O B}) \\ = \vec{O C} - \vec{O A} \\ = \vec{A C} \end{aligned}

$\vec{v} \pm \vec{w} = \vec{w} \pm \vec{v}$

$(\vec{u} \pm \vec{v}) + \vec{w} = \vec{u} + (\vec{v} + \vec{w})$
