random math problem

[berry05]

i tried searching phpfreaks and i found a thread that was kind of what i needed but not quite...anyways...

 

I'm trying to make a code so that when someone clicks a generate button a random math problem shows up. a polynomial math problem. I know i have to type the polynomial math problem in my code but how do i make it so that when someone clicks generate problem a problem shows up?

[Maq]

How are the problems stored?

If you're setting the $question# vars to either be the value or false, why does your else if statement doesn't check for if it's false? And do you need $_SESSION for this?
