Help:Math

This extension is enabled by default on Fandom.

Math formulas can be displayed on articles using the <math> tag.

For the technically inclined, MediaWiki (which is used by Fandom wikis) uses a subset of AMS-LaTeX markup, a superset of LaTeX markup which is in turn a superset of TeX markup, for mathematical formulas.

Instructions

Source

  • Open source editing mode for an article.
  • Write your math code in the following format: <math>math to be displayed</math>.
  • For details on how to write the math formulas themselves, see Help:Displaying a formula on Wikipedia.

Visual

  • Open visual editing mode for an article.
  • In the insert dropdown, select "Math formula".
  • In the middle will be an editor similar to source editing, but you can choose options from the bottom to insert into the formula.

Examples

The equation '3 x 2 = 6' can be displayed using:

<math>{3 ~ \times ~ 2 ~ = ~ 6}</math>
Which generates this:

In-line formulas require display="inline" attribute:

<math display="inline">V = \frac{4}{3}\pi R^3</math>
Which can be used to generate this:
The volume of a sphere is .

Regular text can be added to a math formula like so:

<math display="inline">\rho_{\text{Air}} = 1.225~\text{kg/m}^3</math>
Which will render like this:

If you want to display something like 3 to the power of 12, this will not work:

<math display="inline">3^12</math>
It will display as this:
Instead, group the 12 with { and }, like this:
<math display="inline">3^{12}</math>
It will display as this:

Notes

  • Large formulas may become wider than the maximum page width. Consider breaking them into multiple lines when possible.
    • Another solution is to place the formula inside a simple div with "overflow-x:scroll" set, so that a scrollbar show up. For example:
<div style="overflow-x:scroll;">
<math> ... </math>
</div>
  • In-line formulas can have poor vertical alignment relative to the rest of the text. A work-around is described on Wikipedia.
