**Welcome to the math homework help subreddit.**

This subreddit is mainly for getting help with math homework. However, math questions of all kinds are welcome. Please read the FAQ before posting. Please be careful with your superscripts, see here for advice.

**Using LaTeX**

### If Greasemonkey doesn't work **try this one**

Plugin based on TeX The World and modified by wsdenker.

`[; e^{\pi i} + 1 = 0 ;]`

You may need to add four spaces before, or put backticks around, math fragments.

**Custom superscript and subscripts (credit: /r/homeworkhelp):**

Here's the syntax:

- *_sub_* makes
*sub* - *`sup`* and \^(sup) both make ^(sup)
- *_sup_`sup`
*makes**sub*`sup`

* - *`sup`_sub_* makes
`sup`

*sub*

If you have trouble with spacing, add some blank spaces with \

```
2300H becomes 2300 H
```
