Talk:Natural number

Mathematicians haven't decided on the official definition of $\mathbb{N}$. --Chess64 18:06, 19 June 2006 (EDT)


Notation like $\mathbb{N}$ should definitely be left for the intermediate section of the article. The Introductory section should include a more plain-English definition.--MCrawford 21:19, 21 June 2006 (EDT)
