Great app. Would be great if you could choose the level of difficulty of the problems. My son has mastered the multiplication questions and he needs more difficult ones now. Or perhaps the user could choose the range of numbers in the questions. (Egs 0-12 for multiplication/division Qs, 0-100 for add/subtraction Qs)
