Miramath is an Open Source project inspired by the MathCad mathematical application. The main user interface consists of a page into which mathematical expressions can be entered or edited and then evaluated. It features a Wysiwyg equation editor, automatic evaluation of equations, integrated plotting, symbolic algebra using Sympy, and numerical computations using Scipy.
Wise is an experimental Web-based notebook and simple computer algebra system based on the Pure programming language. The goal is to provide a digital scratchpad that makes manipulating symbolic expressions fast, accessible, and extensible. Wise is a bottom-up approach to symbolic math written entirely in C and Python. It does not depend on any external math software or libraries (such as Maxima, Axiom, Mathematica, etc.).
The Java Algebra System (JAS) is an object oriented, type safe, multi-threaded approach to computer algebra. JAS provides a well designed software library using generic types for algebraic computations implemented in the Java programming language. The library can be used as any other Java software package, or it can be used interactively or interpreted through a Jython or JRuby front end. The focus at the moment is on commutative and solvable polynomials, power-series, multivariate polynomial factorization, Gröbner bases, and applications.
