[an error occurred while processing this directive] The major purpose of a Computer Algebra System (CAS) is to manipulate a formula symbolically using the computer. For example, expanding, factorizing, root finding, or simplifying an algebraic polynomial are some of the common uses of CAS. However, many systems listed here have gone far beyond that and also offer other functionalities like numerical calculation, graphics, and simulations. They are included in this section because their very original, and still their most distinguishable capability is performing computer algebra. Search SAL:
