Vector Question...

algebra coordinates

I need to answer a question, using maple, mathcad, or a similar algebra solver.

I have a little experience in Maple, and thought it would be easy, buts its not, here is the question.

The question is

-----

Let P and Q be two points in the x-y plane with coordinates (1,2)  and (1,-1) respectively with respect to an origin O. Express OP, OQ and QP in the form Ai  + Bj   where A and B are scalars. Let R be a point on OP so that OR = 1/3OP . Find OR and QR in terms of i  and j .

-----

I have no idea how to do this.
