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.

# /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.)

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.
