Proposition 1.2.7: Adding complex numbers geometrically
For any complex numbers z and w you can find the sum
z+w by attaching the vector w to the tip of the
vector z and completing a paralellogram. The diagonal of that
paralellogram is the vector z+w.
To find the difference z-w, reverse the vector w and
You can easily verify this by writing z and w as
vectors in R2.
