Talk:Division by zero

"Any number equals 0/0"[change source]

While I do not know how to address this problem in a "simple" manner, a "simple" answer is not an excuse for incorrect information. According to many standards, 0/0 is not equal to "Any number." In fact, 0/0 is not even equal to 0/0, as NaNs are defined to not be equal to each other. It is true that there are an infinite number of solutions for A * B = C where B and C = 0, however translating that into A = 0/0 meaning that every number equals 0/0 is just plain wrong. 68.205.253.132 (talk) 09:06, 25 March 2009 (UTC)[reply]

Major rewrite[change source]

Hello.

I recently performed a large number of edits to this article. I removed the entire signs section, which seemed entirely irrelevant (as well as the last paragraph, which was entirely about multiplication by 0), and did major rewrites of the other sections, to greatly improve clarity (Look at the old versions), accuracy, and relevancy. Any objections? Daryl7569 (talk) 23:59, 15 May 2009 (UTC)[reply]

Not always undefined[change source]

0/0=undefined

x/0=infinity

x=any number except 0 —Preceding unsigned comment added by 96.52.34.191 (talk) 23:49, 3 September 2016 (UTC)[reply]

I think the article adequately explains that x/0 is infinity, but it also explains that infinity itself is undefined. In mathematics, the word "undefined" does not mean there is no explanation for the word (you and I understand the concept of the word "infinity", after all) but that it is not a concept that can be plugged into mathematical formulas.
