Algebra Diagrams: A HANDi Introduction
A diagrammatic notation for algebra is presented - Hierarchical Algebra Network Diagrams, HANDi. The notation uses a 2D network notation with systematically designed icons to explicitly and coherently encode the fundamental concepts of algebra. The structure of the diagrams is described and the rules for making derivations are presented. The key design features of HANDi are discussed and compared with the conventional formula notation in order demonstrate that the new notation is a more logical codification of introductory algebra.
