Section 0.4 Fonts and Typesetting

We use different fonts (typefaces) to represent different things.

Mathematical formulas are typeset in \(italics\text{.}\)

For some important mathematical structures we use a character set called black board bold, in particular we use \(\mathbb{A}\text{,}\) \(\mathbb{N}\text{,}\) \(\mathbb{P}\text{,}\) \(\mathbb{W}\text{,}\) and \(\mathbb{Z}\text{.}\)

While variables are typeset in \(italics\) we typeset characters and text that we manipulate in courier (the typeface of most mechanical typewriters).
