Welcome
Welcome to ProofWiki! Since you're new, you may want to check out the general help page. It's the best first stop to see how things are done (next to reading proofs, of course!). Please feel free to contribute to whichever area of mathematics interests you, either by adding new proofs, or fixing up existing ones. If you have any questions please feel free to contact one of the administrators, or post your question on the questions page.

Here are some useful pages to help get you started:
 * Community Portal - To see what needs to be done, and keep up to date with the community.
 * Recent Changes - To keep up with what's new, and what's being added.
 * Check out our house style if you are keen on contributing.
 * Main Page talk - This is where most of the main discussions regarding the direction of the site take place. If you have any ideas, please share them!

Cheers!

Notational style
I direct you towards Help:FAQ which discusses notation, and offers a reason for why I reverted your recent change to Pi is Irrational. --prime mover (talk) 07:47, 17 October 2013 (UTC)

To my knowledge Z+ was the common notion, Z>0 does look unneccierily long and cumbesome if you ask me EmperorZelos (talk) 08:14, 17 October 2013 (UTC)


 * It's ambiguous. Some usages of $\Z_+$ mean $\left\{{x \in \Z: x \ge 0}\right\}$ thus including $0$ (where $\Z_+^*$ means $\left\{{x \in \Z: x > 0}\right\}$) and some do not. In order to allow complete unambiguity of expression, we are attempting consistently to use the form $\Z_{>0}$ and its related expressions, e.g. $\Z_{<0}, \Z_{\ne 0}, \Z_{\ge 0}$ and so on.


 * This also allows the compact extension to this notation allowing such things as $n \in \Z: n \ge m$ to be expressed as $n \in \Z_{\ge m}$ and so on. --prime mover (talk) 09:46, 17 October 2013 (UTC)
