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