ScAS is a computer algebra system developed in Scala. Scala has some more features than Java to optimally support the implementation of a computer algebra system. The basic structure of ScAS is developed in cooperation with the basic structure of JAS, see the co-authored papers in the Documentation section. ScAS is also a successor of jscl-meditor.

jscl-meditor Java symbolic computing library and mathematical editor. The goal of this project is to provide a Java symbolic computing library and a mathematical editor acting as a front-end to the former. There are several computer algebra systems available on the market, most of them developed in other languages, mainly C/C++ and Lisp. But the benefits of using Java in symbolic computation are great. Aside from being widely used and to comply with various standards, this language has two features of concern: readability and portability.

MathEclipse is a Java Computer Algebra system. MathEclipse has functions for arbitrary-precision integer arithmetic, matrices, vectors, finite sets, derivatives, pattern-matching rewriting rules and functional programming.

Symja - a symbolic math system written in Java based on the MathEclipse libraries. Features: arbitrary precision integers, rationals and complex numbers, polynomials, differentiation, pattern matching and linear algebra.

GeoGebra is dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. On the one hand, GeoGebra is an interactive geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra view corresponds to an object in the graphics view and vice versa.

Macaulay2 can compute Betti numbers, Ext, cohomology of coherent sheaves on projective varieties, primary decomposition of ideals, integral closure of rings, and more.

Axiom is a general purpose Computer Algebra system. It is useful for research and development of mathematical algorithms. It defines a strongly typed, mathematically correct type hierarchy. It has a programming language and a built-in compiler. In 2007, Axiom was forked into two different open source projects: OpenAxiom, and FriCAS.

FriCAS is an advanced computer algebra system. Its capabilities range from calculus (integration and differentiation) to abstract algebra. It can plot functions and has integrated help system.

OpenAxiom is an open source platform for symbolic, algebraic, and numerical computations. It offers an interactive environment, an expressive programming language, a compiler, a large set of mathematical libraries of interest to researchers and practitioners of computational sciences.The Modula-2 Algebra System (MAS) is an experimental computer algebra system, developed at the University of Passau. MAS combines imperative programming facilities with algebraic specification capabilities for design and study of algebraic algorithms. It contains a large library of implemented Groebner basis algorithms for nearly all algebraic structures where such methods exist. MAS further includes algorithms for real quantifier elimination, parametric real root counting, and for computing in (noncommutative) polynomial rings.

Starting point for the development of MAS was the requirement for a computer algebra system with an up to date language and design which makes the existing ALDES / SAC-2 algorithm libraries available. At this time there have been about 650 algorithms in ALDES / SAC-2 and additional 450 algorithms related to Gröbner bases developed on top of ALDES / SAC-2. The tension of reusing existing software in an interactive environment with specification capabilities contributes most to the evolution of MAS.

The resulting view of the software has many similarities with the model theoretic view of algebra. The abstract specification capabilities are realized in a way that an interpretation in an example structure (a model) can be denoted. This means that is is not only possible to compute in term models modulo some congruence relation, but it is moreover possible to exploit an fast interpretation in some optimized (or just existing) piece of software.

MAS is a predecessor to JAS with respect to the main concepts, however JAS was rewritten from scratch.to be continued
