Algebrus is meant for everybody who needs to do either scientific analysis or just doing school homework. It provides user with numerous mathematical and analysis functions as well as allows unlimited extension of its functionality by means of user-defined types, constants, operators, routines, and libraries.

Its extensibility is based on a built-in simple to learn and yet powerful programming language XPascal. Algebrus can be used both as a simple "evaluate-while-typing" calculator and as a powerful mathematical analysis application, which includes 2D and 3D graphic plots of functions and data, command line execution console, and a syntax-highlighted XPascal editor as a part of the integrated development environment (IDE).

Calculations include:

• Vector and matrix operations and functions
• 2D and 3D graphic plots of function and data
• More than 50 built-in mathematical functions
• User-programmed procedures and functions
• User-defined types and operators
• Solving of linear algebraic systems
• Solving of ordinary differential equations
• Inversing matrices, Fourier analysis
• Statistical data analysis

Using special Plotter tool, creating 2D and 3D graphic plots of functions requires no programming skills whatsoever. Evaluator tool allows simple and interactive evaluation of functions and procedures. It fully supports interfaced constant declarations that appear in the Evaluator as Parameters section
