Unlike numerical input problems, which only allow integers and a few
select constants, math expression problems can include more complicated
symbolic expressions.

Unlike numerical input problems, which only allow integers and a few select constants, math expression problems can include unknown variables and more complicated symbolic expressions. The grader uses a numerical sampling to determine whether the student's response matches the instructor-provided math expression, to a specified numerical tolerance. The instructor must specify the allowed variables in the expression as well as the range of values for each variable.
.. warning:: Math expression input problems cannot currently include negative numbers raised to fractional powers, such as (-1)^(1/2). Math expression input problems can include complex numbers raised to fractional powers, or positive non-complex numbers raised to fractional powers.
