further bonus from the topic is the discussion of 'operational
rules' which can be related to the rules of numbers, especially
the commutative and associative law. It may be necessary
to explain the need for the two types of representation,
(x,y) for the point and G) for the vector from (0,0) to
(x, y). Although this notation is complicated it is not
difficult. Remember that the topic will be presented again
and that exploration is more important than memorizing at
this stage.
