<pre>''f'':&nbsp;''X''&nbsp;×&nbsp;''Y''&nbsp;→&nbsp;[0,&nbsp;1]</pre>
However, this results in cumbersome source code which can be difficult to edit. Using this template, the same result can be achieved with:
<pre>{{mbox| ''f'': ''X'' × ''Y'' → [0, 1] }}</pre>
===Dealing with equations===
Because of Wikipedia limitations on templates, mbox doesn't function as stated above if the math contains an equals sign. In this case, the following syntax should be used:
<pre>{{mbox|eq= 2''x'' + 3''y'' + 5''z'' = 7 }}</pre>
This longer syntax also works for non-equations.
