9. Mathematics

As mentioned in the introduction, LaTeX is
particularly good at typesetting mathematics. In order to
use any of the maths commands we need to be in one of the
mathematics environments. There are two
basic types of mathematics: *in-line maths* and
*displayed maths*. In-line maths is mathematics that
occurs within a line of text, for example:

Displayed maths is mathematics that occurs on a line of its own. For example:

The maths environments switch to LaTeX's “math mode”, which uses specialist maths fonts and spacing rather than just using an italic font.

If you want to typeset any mathematics, I strongly advise using the
`amsmath` package:

`\usepackage`

`{amsmath}`
This chapter is just an introduction to typesetting mathematics in
LaTeX. If you want a comprehensive guide, I recommend you read Math Mode
by Herbert Voß [21], which can be access via
`texdoc` (see §1.1. Class and Package Documentation):

texdoc mathmode
