A real number is complex because any complex number is of the form a+bi. The number is real if b = 0. Ex: 4 is a complex number since 4 = 4+0i

However, a complex number such as 3+2i is NOT real since it has that imaginary part '2i' added on. So not all complex numbers are real (some are, others are not)
