Open Source Free Pascal Computer Aided Instruction (CAI) Software

GraphCAD is a pseudo 3D Computer Aided Design (CAD) program to modeling dinamic and static objects, basics on graph theory. GraphCAD may be used as GIS, Medical Disgnostic, Engineering, Education and Mathematical modeling tool.

RekenTest is freeware educational software to practice arithmetic skills. It supports basic arithmetic operations like addition and subtraction, the muliplication tables and so on, as well as more advanced arithmetic operations like decimals, money problems, percentages and fractions. The software has lots of options and lets you organize your classroom with tasks and groups.

Personal research achievements from the authors presented here in the form of symbolic Algebra and non-numerical analysis algorithms implemented in C/C++, Java, and/or Pascal. As part of a more wide, simple, powerful and robust CAS enviroment under development, new code will be continuously added up to this repository. The authors give their welcome and encouragement to everyone interested in bring some kind of collaboration.
