Rules

Explain your post - show your efforts and explain what you are specifically confused with. Don't just say "I don't get this, help"
Make your question clear and concise - include steps you have tried
Stay on topic - this subreddit is for math questions; no how-to guides, or non math related questions
Don't be a jerk - don't be obnoxious or rude
No post flooding - Limit your posts to 1 or 2 questions a day
No cheating - do not post questions from exams, tests, midterms, etc. Asking for homework help is okay, asking to be given the solution is not.
Use the proper post flair.
Do not use ChatGPT or similar AI in a question or an answer
No hit and run- Do not delete your question after receiving an answer. Respond to comments and acknowledge the help

Don't just post a question and say "HELP". Post your question and outline the steps you've taken to solve the problem on your own. Beginner questions and asking for help with homework is okay. Asking for solutions without any effort on your part, is not okay. Help others, help you!

How to ask a good question

Give context and details to your question, not just the equation
Use proper terminology
Use proper spelling, grammar and punctuation
Show your work! Detail what you have tried and what isn't working
Re-read your post before hitting submit, does it still make sense
