The four complex number arithmetic models in this item show the addition, subtraction, multiplication and division of a complex number z2 to all numbers z1 of a point grid. The z1 and z2 are changed and the grid is moved by dragging the tip of the z1 and z2 arrows in the z-plane. The parallelogram for the vector construction representing the arithmetic operation are drawn on the simulation's right-hand side.

Complex Number Arithmetic models are part of "Learning and Teaching Mathematics using Simulations – Plus 2000 Examples from Physics" ISBN 978-3-11-025005-3, Walter de Gruyter GmbH & Co. KG
