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 its answers to mathematical questions; even if you subscribe to ChatGPT Plus and use its Wolfram|Alpha plugin, it's much better to just 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.)

• 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.
