The absolute value |z| = Va² +b² represents the distance of z from 0, and more generally, u – v| represents the distance between u and v. When combined with the distributive law, u(v – w) = uv – uw, a geometric property of multiplication comes to light. 1.2.4 Deduce, from the distributive law and multiplicative absolute value, that |uv – uw| : lu||v – w|. Explain why this says that multiplication of the whole plane of complex numbers by u multiplies all distances by |u|.
