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 is drawn on the simulation's right-hand side. The default model shows that complex multiplication rotates the grid in the complex plane. Addition, subtraction, and division models are cataloged as supplemental documents.

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
