These systems are becoming very comprehensive, including more and more numerical methods (in addition to symbolic), and powerful graphic and visualization capabilities.
If you have a modeling or problem solving task in which the natural language is mathematics, then these systems are very powerful.
Essentially arbitrarily accurate integer arithmetic is possible because integers are represented as arbitrarily long strings of symbols, and arithmetic is carried out in software, not in hardware.
