And there is another problem with those 4 options kind of questions. You can "cheat" quite easily by just looking at the last digitsitslate wrote: And I don't want to just give the user 4 options each time. Eventually, he will just do trial and error or even worse: in memory segments he can memorize the buttons instead of the numbers.
e.g.: 764772*56573
A) 43265446356
B) 45757588574
C) 54433884488
D) 86855444855
Looking at just the last digits of the question gives you 2*3 which is 6 and you know that the correct answer is A because it's the only option ending with a 6. Cheating could be prevented if the last digits of the options were all 6 though...
