CoCoA System System for computer and commutative algebra. It computes Gröbner bases, syzygies and minimal free resolutions, intersections, divisions, the radical of an ideal, Poincaré series, Hilbert functions and factorization of polynomials. 
Aldor Typecomplete, stronglytyped, imperative programming language with a twolevel object model of categories and domains. Improved extension language for the Axiom algebra system; captures the highlevel objects and relationships in modern mathematics. 
LAPACK  Linear Algebra PACKage Provides routines for solving systems of simultaneous linear equations, leastsquares solutions of linear systems of equations, eigenvalue problems and singular value problems. Written in Fortran77. 
Mathscribe Graphing and mathematical modeling program for algebra, trigonometry and precalculus classes, as well as mathematical model scientific data. Algebra computer lab assignments including linear equations, systems of linear equations, quadratic equations. 
Singular Computer Algebra System for polynomial computations with special emphasis on commutative algebra, algebraic geometry and singularity theory. The main computational objects are ideals/modules over very general polynomial rings over various ground fields. 
JACAL Symbolic mathematics program  manipulates and simplifies equations, scalars, vectors and matrices of single and multiple valued algebraic expressions containing numbers, variables, radicals and algebraic differential and holonomic functions.
