# 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 TEX editor, called the 'TEX Box', which appears in a popup window when you click on the button at the left of the edit toolbar.

The TEX Box is also available on its own special page.

## Inserting Formulas

Inserting TEX markup is done using $...$ tags. For example, to display the following quadratic formula

${\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}}$

you could use the markup

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

## Consistent Use of $...$

It is strongly advised that $...$ be used around all mathematics added to this wiki, even if the assistance of TEX 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.
