Is it possible to work with complex numbers in Maple T.A?

How could you for instance make a question where two complex numbers in polar form should be added. For instance (10<30deg)+(15<-10deg). I'm thinking of letting answers be in two fields, one for the absolute value and one for the angle but I would like to use random numbers in the two complex numbers to be added and would prefer to be able to use complex math in calculating the right answer.

I try to make a question with an equation with numbered variables. This works fine when evaluating:

y=x1/x2

I need to have the lefthand variable indexed also like this:

y2=x1/x2

When entering y2=x1/x2 as the answer Maple TA won't evaluate it as a correct answer!?
