MathXpert is software to help people learn algebra, precalculus, or calculus. Here's a typical solution in progress. The student
has already taken three steps. The part of the expression that changed from the previous line is shown in red.
MathXpert displays solutions
in the classical twocolumn format, with the justification for each step in the righthand column.


What happens next depends on whether the student knows what to do next. If so, MathXpert provides tools for
carrying out the desired mathematical operation. If not, then the student can get help. You can see both possibilities:
click here to see what happens if the student knows what to do, or
click the Hint, Autostep, Showstep, or AutoFinish button to see the
kinds of help available.
