< MediaWiki User Guide

You can enter mathematical formulas into a wiki, using a math tag, such as:

<math>\sqrt{2}</math>

The formulas are marked up in the TeX markup, the markup of a complex typesetting system specialized on mathematics.

Before you start writing formulas in this markup, you can consider writing the simpler ones in HTML and wiki markup, such as:

f(x) = b + c / d

which is marked up as 

 ''f''(x) = ''b'' + ''c'' / ''d''

Examples

To get started, follow the examples below.

  \vdots & \ddots & \vdots \\ 
  0      & \cdots & 0
\end{bmatrix}</math>
8. 
<math>\begin{pmatrix}
  x & y \\
  z & v 
\end{pmatrix}</math>

Greek and symbols

There is a way of marking up Greek characters and special symbols, as the following table shows.
