Hello, I'm DVdm. Your recent edit to the page Division by zero appears to have added incorrect information, so I removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, DVdm (talk) 08:43, 20 March 2013 (UTC)

Thanks: As I remember, I saw O/O referred to as an undefined number, which I changed to read 1/0. O/O = 0, as does 0/1; whereas 1/0 is an undefined number;I gave my source as p 25 of Ballou & Steen's PLANE & SPHERICAL TRIGONOMETRY WITH TABLES,second edition. The re-edited version goes towards this, but has the bizarre notation of infinity inverted, an affectation that obscures understanding the matter. 0/0 No part of nothing, 1/0 some part of nothing; 0/1 no part of something. Infinity is not nothing.

Hello, and thank you for your contributions to Wikipedia. I've noticed that you have been adding your signature to some of your edits to articles, such as the edit you made to Gaia hypothesis. This is a common mistake to make and has probably already been corrected. Please do not sign your edits to article content, as the article's edit history serves the function of attributing contributions, so you only need to use your signature to make discussions more readable, such as on article talk pages or project pages such as the Village Pump. If you would like further information about distinguishing types of pages, please see What is an article?. Again, thank you for contributing, and enjoy your Wikipedia experience! Thank you. ☾Loriendrew☽ ☏(talk) 12:05, 23 January 2014 (UTC)
