Teachers! If you're using this site to generate an assignment for your class, please let me know! I'd love to create a list of teachers and schools that have used this list. I'd also like to discuss the possibility of having your class submit some equations that they've made up. I'll post featured ones with credit for the student and the school.

Students! If you found this site because your teacher has assigned these equations for you (from this source or any other), I'd still love to know it! Please include information about your age, grade level, location, and school. Encourage your teacher to contact me, and your class may well be featured here.

Click here to request some hints if you can't figure out the answers, but not until you've given this a real shot. Ask your friends, family, neighbors, coworkers, and anyone else you can think of to help you come up with answers. It truly is much more fun that way!
