Okay... I see the value of it, not sure why it's not getting more well deserved attention. I'm not a teacher myself though I have worked as a student teacher before, but wow... this is awesome. I shared it with my teacher friends and my programmer group of 200,000 -- probably some teachers there. You could monetize this if you wanted and expand beyond math to either come up with your own questions or those that are submitted by a community of teachers.
