```The questions that I created that use Maxima to check if the answer is correct, I can't seem to get the answer to show up in the answer key of the TeX version.  I placed the solution in the answer display part of the problem and it still isn't showing up.

Print Options that I used:
Problem Type: Exam Problem

Any ideas how to do that?  Below is an example of a problem.  Thanks.
