I am a high school Math, Physics and Chemistry teacher. I once taught five different classes: AP Calculus BC, AP Physics B, Physics, Pre-calculus and Chemistry. Since I have to teach 34 hours a week, plus tutor a couple of very bright kids, I am unable to give answers as detailed as most top contributors do. What I do here is to spend the least amount of time to give you some ideas to help you to do math problems with average difficulty. Most of time, my approach is short and simple but hard to understand at first glance. But if you try to get it, you can learn more. Also, if you don't quite understand my approach, email me. Most of time, I'll give you more explanations once I receive your email. But don't email me your whole set of homework.
