      2. Give 100% for answer formula "{a}*{b}"
      3. Give 50% for answer formula "-{a}*{b}" – note the negative sign
      4. Set unit handling to "Units are optional..."
      5. Add a unit (e.g. "cm")
      6. On the next page "Choose wildcards dataset properties" just click "Next page" button.
      7. Confirm on the next page "Edit the wildcards datasets" in "Answers tolerance parameters" the positive answer is evaluated correctly
      8. Confirm that the negative answer is no longer displaying an "ERROR" message and the answers are correct.

      Negative answers to calculated questions with units are evaluated wrong.

      To duplicate:
      Create a calculated question like: "{a}*{b}"
      Give 100% for answer formula "{a}*{b}"
      Give 50% for answer formula "-{a}*{b}" – note the negative sign
      Add a unit
      On the next page "Choose wildcards dataset properties" select Next button.
      On the next page "Edit the wildcards datasets" in "Answers tolerance parameters" the positive problen is evaluated correctly, the negative problem is not, saying "ERROR: Correct answers etc." is outside limits, though it is not.
