Hi,

I'm trying to have students solve a simple fraction problem like  $a - ($b + $c)  /   ($d - $e), where each letter is a programmed variable and where $d, $e and its difference do not give zero.  The answer could be either a fraction, or an integer (if the fraction can be simplified).  If I use the Maple-graded type of question, this is possible, but the student can also write the initial fraction problem and get a good mark for it !  If I use numeric, it does not allow the use of the sign / for the fraction. I tried using the question-defined menu, but again with no success. What is the best way to do this ?
