The following paste formatting changes have been made to pull requests, issue comments and wikis:

- Spreadsheet cells and HTML tables will render as Markdown tables
- Any copied text containing links will render the links in Markdown

All of this formatting can be disabled when pasting using the keyboard shortcut: `cmd|ctl + shift + v`

or `cmd|ctl + shift + Alt + v`

.

delimiters).
To add math as a multiline block displayed separately from surrounding text, start a new line and delimit the expression with two dollar symbols `$$`

.

```
**The Cauchy-Schwarz Inequality**
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
```

To include a math expression inline with your text, delimit the expression with a dollar symbol `$`

.

`This sentence uses `$` delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$`

GitHub's math rendering capability uses MathJax; an open source, JavaScript-based display engine. MathJax supports a wide range of LaTeX macros and a number of useful accessibility extensions. For more information, see the MathJax documentation and the MathJax Accessibility Extensions documentation.

Some users have previously used a workaround to generate images of mathematical expressions through API requests. Images generated this way will remain viewable, but this technique will no longer work. Going forward, expressions should be written directly in Markdown using LaTeX syntax as described above.
