Free algebraic equations software for windows

Algebrus is an award winning application for scientific and general purpose calculations.
It provides user with numerous mathematical and analysis functions as well as allows unlimited extension of its functionality by means of user-defined types, operators, routines, and libraries.
Its extendibility 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 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).
Algebrus software as well as XPascal language were developed by Dr. Vladislav Apostolyuk.

This is a neat little program that will graph all linear equations. Equation Graph will also generate ordered pairs for graphing on paper manually. This is great for checking your algebra homework. Equation Graph is designed and programed by an Algebra student. Future versions of this program are in theworks.

Equation(expand) 3.3 offers a stable and advanced software made for the purpose of acquiring the expanded result of "a2+2ab+b2", when (a+b)2 is set accordingly this software is made for the purpose of acquiring an expansion of an equation. And the acquired equations can be added or expanded by files-works each other. The straight lines equation passing several points on X-Y plane or 3-dimension and having minimum distance were showed on the document of "About equation software.

ReactOS Calc is a scientific calculator that has been written with the purpose to be a clone of calculators included into MS Win32 operating systems. It has a similar user interface and keyboard shortcuts.
ReactOS Calc is a program for evaluating mathematical, financial and statistical calculations.
Main features:
- Internal precision with 17 decimal numbers.
- Robust RPN (reverse polish notation) engine which allows a virtually unlimited number of arithmetic and algebraic sub-expressions.
- Two different interfaces: standard or scientific.
- Many common arithmetic, algebraic and statistical functions are included.
