# Help:Mathematical Symbols

POV-Wiki has the standard MediaWiki math extension installed, which allows the use of a subset of LaTeX syntax.

## Inserting Formulas

Inserting math 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 markup 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.
