The following languages are commercial symbolic algebra packages. They have libraries and features which simplify complex programming, and can be used to teach. In particular, they allow integer computation with numbers of arbitrary size. Their nature as interpreted languages does make them too slow for very large computations, though. Note that PARI is a freeware package.
