That shouldn't be hard -- you would have to take the input as a string,
then _parse_ it, stripping off one layer of operations at a time. Good
application for recursion. Use a function, not a progam, on the TI-89.
A good programming project, probably would take about one weekend's worth
of work (not _my_ weekend, sorry).
