The OP was looking for "explanation of complex numbers"

You won't explain anything by talking about 2D points only

But you can if you specify only how they behave with addition and multiplication (see my others posts)

The OP was complaining about the explanation that complex numbers "have a real and an imaginary part", because it mean nothing to them. It is alright, then, to clarify that this just means that they are points in the plane, and some operations will be defined on these points.
