Thanks Chris.  That solved the problem.  Though I don't really understand 
what I just did.  I sort of blindly copied the code from complex.rb.

What does #coerce? do.  What does that 'super' do?  In particular, how 
does that solve the addition problem?

Once again, thank you very much.  I never would have figured that out.
