The Reals are a subset of the Complex.

In the 'complex plane' there is a real axis and an imaginary axis. The plane
then represents the set of Complex numbers and operations are modeled by
vector operations. How cool is that?

Imaginary numbers are of the form 0+bi. Nothing special there.

1) Number System having two subsets: Real(rational and irrational) and
Imaginary(which includes complex numbers) OR

2) Complex Number System having two subsets: Real and Imaginary
