There are other rules that you can find at Rules for asking questions, but do pay particular attention to these:
- Daily limit of 4 problems per day. All tutors on algebra.com are FREE.
- One problem per submission. Do not dump your whole homework in one question.
- If you can, show what you have tried. Tutors like students who try. If a tutor gives you credit for work shown, that problem would not count towards your daily limit.
