The position of a complex number can be described using Cartesian coordinates (real & imaginary parts) or alternatively it can be described using Polar coordinates (mod arg form).
lesson notes:04 mod arg form
If we can’t place complex numbers on the number line, how do we represent them visually? The is using a two dimensionsal picture known as the Argand Diagram.

With the use of imaginary numbers, all quadratics can be solved. Also we look at finding the square root of any complex number.
