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.
