    This video shows very clearly and concisely what complex numbers are and what they mean geometrically using a number line and protractor. Complex numbers, their addition and multiplication are shown on a blackboard in a way analogous to vectors in the plane. Finally, a stereographic projection of the complex plane is shown. A truly great place to begin understanding complex numbers.
