Template:Theorem

Formats math theorems, for example:

 {{theorem|note=Existence of an irrational number|contents=<math>\sqrt{2}</math> is irrational.}}

yields

Theorem (Existence of an irrational number) — [math]\displaystyle{ \sqrt{2} }[/math] is irrational.

Note: To include the character |, it must be escaped as {{!}}, unless it appears inside preformatted text (such as a <syntaxhighlight> or <math> tag).
