# Help:Math

Math formulas may displayed on Wikia pages using a built in $tag found in MediaWiki, the software Wikia runs on. This tag is enabled by default and can be used across all wikias. For the technically inclined, MediaWiki uses a subset of AMS-LaTeX markup, a superset of LaTeX markup which is in turn a superset of TeX markup, for mathematical formulae. ## Step-by-Step • You need to first be in source editing mode on an article. • You must use the following format: [itex] math to be displayed$.

### Simple example

3 x 2 = 6 can be displayed as ${3 ~ \times ~ 2 ~ = ~ 6}$ to generate

${3 ~ \times ~ 2 ~ = ~ 6}$

### Notes

• Large formulas may become wider than the page width allowed by Wikia's wikis and will overlap the right hand side-rail information, if your math formula is near the top of the page you wish to use.
• One solution is to place the formula inside a simple basic table, with no borders or any formatting.
• Tables that get too wide will show the Pop-Out button, so that the whole table can be seen.
Here is an example:
{|
| $math formula goes here$
|}

• In-line formulae often have poor vertical alignment relative to the rest of the text. A work-around is described here.
