Welcome to our tutoring boards! :) This page summarizes main points from our posting guidelines. As our name implies, we provide math help (primarily to students with homework). We do not generally post immediate answers or step-by-step solutions. We don't do your homework. We prefer to help...

As this says, please tell us where the problem comes from (e.g. a test problem after you've learned certain topics, or a sample contest problem at a certain level, or whatever); and show us what you have tried. As it is, we have no idea what you know and where you need help, or what kinds of math to try using. We aren't here to just give you an answer, but to help you figure it out.
