PQRS is a parallelogram with P->Q=a and P->S=b. Find S->Q in terms of a and b. N is a point between S and Q, where SN:NQ is 3:2, find N->R

Vectors are special in that they have a direction as well as magnitude (size).

To get from S->Q you can go from S->P = -b and then P->Q =a so S->Q = -b + a = a
