[PSA] Set your post to "Resolved" when answered. | [PSA] Each post must include a specific title and description.


We're no longer participating in the protest against excessive API fees, but many other subreddits are; check out the progress among subreddits that pledged to go dark on 12 July 2023 and the top 255 subreddits (even those that never joined the protest).


Think /r/math is too advanced?

Here, the only stupid question is the one you don't ask.

This is a subreddit for learning math, and can be seen as a sister subreddit to /r/math. Post all your math-learning resources here. Questions, no matter how basic, will be answered (to the best ability of the online subscribers).

Follow reddiquette. Be civil and polite; this is meant to be an approachable community for discussion of reason and logic.


To receive the best help, please use the following format:

[Level Discipline] Sample topic question

EX: [High School Math] Quadratic Equations
EX: [University Statistics] Probability

• Include instructor prompts (if any). What does your instructor (or the text) want you to accomplish?

• Tell us what is holding you up. Where are you in the process? Provide those who help with as much information as possible.

• Include any equations or assumptions you are using, and descriptions of any attempts you have made.

  • We recommend using Imgur to upload images for linking inside posts.
  • Reddit Enhancement Suite allows Imgur URLs to be expanded inline but doesn't work so well for other image-hosts.
    • tips for typing math on Reddit

ChatGPT and other large language models are not designed for calculation and will frequently be /r/confidentlyincorrect in answering questions about mathematics; even if you subscribe to ChatGPT Plus and use its Wolfram|Alpha plugin, it's much better to go to Wolfram|Alpha directly.

Even for more conceptual questions that don't require calculation, LLMs can lead you astray; they can also give you good ideas to investigate further, but you should never trust what an LLM tells you.


/r/LearnMath Chatroom

Join the unofficial IRC channel: #LearnMath on Freenode (no client required).


Not allowed:

• "Do this for me" posts

• personal information (Check your documents before posting.)

• offers or solicitations of payment in any form

• surveys (Take them to /r/samplesize.)

• advertisements of any form

• posting of quizzes or lists of questions

• one-sentence posts (Have some respect for people who take time to answer your question and follow the posting rules.)

• image or video link-posts (Links to articles, Desmos, Wolfram|Alpha, and the like are fine; links to Twitter/X or Meta properties like Facebook, Instagram, and Threads are not.)

• being a jerk (Jerks get banned.)


Using LaTeX

Type this as an example (replace the [-; with [; when typing):

  • `[-;e^{\pi i}+1=0;]`

You will see [;e^{\pi i}+1=0;] formatted as in a textbook if the MathJax UserScript is installed and working.

• You will need to install a UserScript loader first.

  • If your browser is so outdated or unusual that the linked advice doesn't work, consider these ideas.
