A Template to indicate the level required to comprehend mathematical articles it has 2 parameters:

- required:
- "
**level**" indicates the mathematical ability of the reader from elementary to Einstein (0,1,2,3,4).*The template will not function if this is not set.*

- "
- optional:
- "
**AS**" targets to:**Article**;**S**ection;**P**aragraph; or**D**iagram. The parameter is not case sensitive although its*name*is. If the parameter is omitted the template defaults to: "*article or section*".

- "
