This page explains the Math syntax that can be used in order to format mathematical equations or chemical equations. For example:

 {{x^{12}+x+5}\over{x^{y/z}}}=2

Contents

Syntax

The syntax for displaying a formula is:

<math>{equation}</math>

Where "equation" is replaced by the wanted equation.
