 ... remember the definition of a complex number: Z = a+bi, i^2 = -1

This is not a definition.
Saying i is the imaginary unit that implies that i²=-1 is not a definition in the proper sense of the term.
It is as if we said:
- Mr. Teacher, what is 3?
And the teacher replied:
- It is the cube root of 27.
As a definition, can't we do better.
I say this, I say nothing, I am a crank, let's not forget it.
