# Blackboard Bold¶

Blackboard bold is a typeface which is often used to denote common symbols in maths. In LaTeX, this can be used with \mathbb{ }, putting the text you want in blackboard bold between the { }s. $\mathbb{R}$ is produced with \mathbb{R}.

Some examples:

• $\mathbb{R}$ denotes the set of real numbers
• $\mathbb{Z}$ denotes the set of integers
• $\mathbb{N}$ denotes the set of natural numbers
