A complex “number” is not so much a number as it is a “point”. It is a point that “lives” on the 2D complex plane (as opposed to a real “number” which lives on the 1 dimensional real number line).

There are two components to the complex plane; a real component represented by the real numbers (and we all know what a real number is right?) and an imaginary component represented by the imaginary numbers (and I’m pretty sure that many of you DON’T know what an imaginary number is, so I will explain this as best as I can).
