# Math Help - Adding Vectors

Just a quick question. In the attachment, I have a parallelogram with a division in the middle. If $\vec{ao}+\vec{oc}=\vec{ac}$, does the same answer occur if the sum is changed to $\vec{oc}+\vec{ao}$?

Many thanks.

Addition is commitive: $\vec{ao}+\vec{oc}=\vec{oc}+\vec{ao}~.$
