# Help:Mathematical Symbols

POV-Wiki supports the standard mediawiki math markup (available via the **√n** button on the edit toolbar). Additionally, it has an interactive T_{E}X editor, called the 'T_{E}X Box', which appears in a popup window when you click on the **∑** button at the left of the edit toolbar.

The T_{E}X Box is also available on its own special page.

## Inserting Formulas

Inserting T_{E}X markup is done using `<math>...</math>`

tags. For example, to display the following quadratic formula

you could use the markup

`<math>x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}</math>`

## Consistent Use of <math>...</math>

It is strongly advised that <math>...</math> be used around *all* mathematics added to this wiki, even if the assistance of T_{E}X is not required (e.g. if the formula could be displayed using standard HTML). This will assist when exporting the wiki into other formats, such as PDF.

## Advanced Use of TeX

Advanced use of TeX is beyond the scope of this help page. Instead, we recommend you consult the comprehensive reference on meta.wikimedia.org.
