Abstract: Mapping diagrams provide a valuable tool for visualizing complex variable arithmetic and functions. Using GeoGebra, I will demonstrate with dynamic diagrams important properties of complex arithmetic and functions. Examples will include complex multiplication and division, linear and linear fractional functions, and some calculus concepts. No prior knowledge of complex arithmetic and functions will be presumed.
