The math environment is used to insert short mathematical expressions in the running text. It renders fractions and Sum-class symbols in a way that consumes less vertical space than the displaymath environment.

It can be used like any other environment with \begin{math}...\end{math} but it is more common to use the shorthand notation $$...$$ or $...$.

Example

 Markup The area of a circle is given by $\pi R^2$.  Renders as The area of a circle is given by .

Comparison with displaymath

 Markup \sum_{i=1}^n  Renders as (in math) (in displaymath)

You can switch between the two types of rendering using \textstyle and \displaystyle.
