This site is here to facilitate mathematical and computational discussion. As such, it is often nice to format your questions and responses as nicely as possible - including typeset mathematics, images, and code as appropriate.

## Sections and other formatting

Textual entry into discourse is based on Markdown - a lightweight markup language that makes formatting relatively easy. To start this particular section, for example, I simply entered:

`## Sections and other formatting`

Creating a bulleted list is as easy as indenting with asterisks. To get this:

- First item
- Second item
- A sub item

Just type this:

```
* First item
* Second item
* A sub item
```

And code like the above is entered by indenting four spaces.

To create typeset mathematics, simply enter a LaTeX snippet. For example, to generate this:

$$\int_{-\infty}^{\infty} e^{-x^2} \, dx = \sqrt{\pi},$$

I simply typed

`$$\int_{-\infty}^{\infty} e^{-x^2} \, dx = \sqrt{\pi},$$`

You can do inline as well. Thus, to generate $f'(x) = -2xe^{-x^2}$, simply type:

`$f'(x) = -2xe^{-x^2}$.`

To upload an image, just look for the upload button in the toolbar. Should look something like this:
