## Homework Statement

Just a quick question. In the attached image, I can say [itex]\vec{am}=\vec{c}-\frac{1}{2}\vec{a}[/itex]. Although subtraction is not commutative, can I also say (relative strictly to vectors) that [itex]\vec{am}=-\frac{1}{2}\vec{a}+\vec{c}[/itex], considering [itex]\vec{am}=\frac{1}{2}\vec{ao}+\vec{c}[/itex]?

Many thanks.
