In Figure 1.2.9(a), the red and green arrows represent the position vectors to points P and Q, respectively.

The black arrow, $\overrightarrow{\mathbf{PQ}}$, the vector from point P to point Q, is the requisite vector.

The gray vector, $\overrightarrow{\mathbf{PQ}}$#, is the translation of $\overrightarrow{\mathbf{PQ}}$ back to the origin.

Vector addition gives $\overrightarrow{\mathbf{PQ}}\prime \+\mathbf{P}\=\mathbf{Q}$, so $\overrightarrow{\mathbf{PQ}}$# = $\mathbf{Q}-\mathbf{P}$.

Translating $\overrightarrow{\mathbf{PQ}}$# yields $\overrightarrow{\mathbf{PQ}}$, the vector from point P to point Q.
