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).
