Mathcounts Marathon
Hows about we start having a problem marathon? Someone posts a problem, and another person answers. Whoever answers needs to post a new one. Don't let the problems go to trig or proofs, or anything harder than middle school. I'll start.
What's the area of a right triangle with sides 3,4, and 5? Edit: You can only post A new problem after your answer is verified as correct by the poster.
