I know about the additive identity of a given addition operation or additive group, but I am not familiar with the usage "additive identity of a number". Is this a common concept? What's the source? Melchoir 10:29, 25 February 2006 (UTC)

I found the article needing work, and supplied additional stuff as necessary to make it a little more accessible. Of course the additive identity only makes sense in terms of the operation of addition, but, in the context of the (real) numbers, the concept is well-defined. I've supplied an informal definition followed by more specificity. Do you think that this article should just start off with a formal definition instead? Xantharius 22:14, 7 August 2006 (UTC)

After more thought, Melchior, you are completely right, and I've made a change to reflect that. Xantharius 23:50, 10 August 2006 (UTC)

[edit] Proposed merge from Zero element to Additive identity

As far as I can tell, these two articles are the same, except that "Additive identity" is a less ambiguous title. Melchoir 10:50, 10 November 2007 (UTC)

Without immediate objection, I'm carrying out the merge and leaving a dab page at Zero element. Melchoir 07:33, 12 November 2007 (UTC)
