I believe that this is a MathObjects issue.

In the quoted Library problem, the correct answer is ($v/$f) * ($cp) + ($c),
which grades correctly.  When students (or instructors) view the correct
answer, it shows as $v/$f $cp with no parentheses.  Since $cp is negative, this
reads as subtraction rather than implied multiplication.
