## Whitespace in math mode

There are a number of predefined commands to add whitespace in LaTeX math mode. These are summarized in the list below.

##### Example usage of medium space `\:`

Here, we use whitespace to separate symbols from regular text. Whitespace commands are available by default. Additional packages are necessary to produce natural number symbol and `\text`

command.

\usepackage{amsmath, amsfonts} $a\:\text{and}\:b \in \mathbb{N}$

##### List of whitespace commands in math mode

% thin space \, \thinspace % negative thin space \! % medium space \: % large space \; % 0.5em space \enspace % 1em space \quad % 2em space \qquad % custom space \hspace{3em} % fill empty space \hfill
