Depends what is meant by a 'numerical answer'. If the questions asks for, say, the magnitude of a force to be calculated, would you consider the answer numerical? How would you specify a force?
 
I can think of something not on you list of three things but I can't think of a hint that doesn't just give you the answer. Perhaps best answer the question haruspex asked you to consider.
