/r/MathHelp is, as the tin says, help with your mathematical questions. If you're willing to learn, we're willing to teach.
Full rules and FAQ are here. Below is a short summary.
RULES FOR SUBMISSIONS:

DO NOT ASK US TO HELP YOU ON TESTS OR EXAMS.

Try SOMETHING before you post here, and post your attempts. See this post for more information. Posts that do not obey this rule will be removed until proof of working is shown. Showing only your final answer is not considered proof of working. Just saying you made an attempt, or how you made an attempt, is not considered proof of working. In other words, show your numbers, if applicable.
(Note: This rule is relaxed for extracurricular problems and questions of clarification.)

Descriptive titles. "High school problem" and "help plz" are not good titles. "[Calculus]Chain Rule Problem" is far better.

Google is your friend. Make sure you first look up definitions you don't know, instead of asking us. Likewise, searching up relevant terms in the subreddit search bar can also answer your question for you.

No advertising for paid services of any sort. Not even paid tutoring.

Posts offering free tutoring should be tagged with [TUTORING]. Similarly, meta posts should be tagged with [META].

Do not delete your posts. Each post contributes to the archive of knowledge mentioned in rule 4.

Please kindly report any posts that violate the above rules. Remember to give a reason when reporting!
RULES FOR ANSWERS:

Do not answer any questions that break rules #1 or #2 above.

When answering, please do not give out the actual answer. It is good practice to guide the student to the solution instead.

When correcting flaws, it's a good idea to use an example to illustrate why the flaw is wrong.
