This sounds to tedious. pi should be pre-defined.

This may be the case for most science instructors, but lon-capa would be
more attractive to math instructors if expressions are allowed.

Perhaps we need two levels of expressions allowed?

The latter. Math instructors should be able to set "expressions allowed"
as the default for the course.
