jazzman1 Posted December 6, 2012 Share Posted December 6, 2012 (edited) Better approach of this is to create a nested or multidimensional array that includes the question and the answer. In other words, you have to create a list, where each item in the list is another list, after that you need to compare that responze with the question's actual answer.

Christian F. Posted December 6, 2012 Share Posted December 6, 2012 Basic mathematics would be more than sufficient for this. You have three variables, two of which needs to be multiplied with each other to match the third. Quote Link to comment Share on other sites More sharing options...
