Problematic text in the android version of the article

In the android app version of the article I just read "I like when my coom spreads into my daddys face ....", as an introductory text before the "quick facts" box. I don't find it on the web and I can't remove it since the page is semiprotected ! Tho-Maigre (talk) 20:35, 22 August 2023 (UTC)

I have absolutely no idea where it is coming from. I've been trying to find it, but to no avail. I think it is being generated by a template, but I cannot figure out how or which. Panamitsu (talk) 21:46, 22 August 2023 (UTC)

It was coming from Module:Technical reasons. Vandalism now fixed. Graeme Bartlett (talk) 07:23, 14 September 2023 (UTC)

Mayan Numeral Zero

Why isn't it recognized that the 'shell shape' is simply a closed fist? Given that a unit is indicated with a glyph of a fingertip or toetip, and 5 is indicated with a glyph of a flat hand, or foot, this closed fist glyph is thematically identical to the absence of a knot representing zero in quipu.

Am I the only modern person who knows what a closed fist looks like? 2600:8800:711E:5600:F903:C9A:7EB9:ED8F (talk) 06:27, 14 September 2023 (UTC)

Well we need it to be published first before we can use this snippet of information. Posting here is not a reliable source. Graeme Bartlett (talk) 07:17, 14 September 2023 (UTC)

Naught-Not merger

Not should be yet another name added, which I'm unable because editting is blocked 31.182.142.83 (talk) 02:46, 3 October 2023 (UTC)

No. "Not" is not a name for zero; it is just that to speakers with the "naught-not merger" (much/most of N America), "not" is a homonym for "nought", which is not generally used in N America. We do not add "ate" as another name for 8. Imaginatorium (talk) 03:30, 31 October 2023 (UTC)

〇 as Zero, has no relation to Zetian.

〇, used for zero, comes from □. The use of □ for zero, began sometime during the Southern Song dynasty. This began to be written as 〇, at least as early as the book 数学九章 (might actually be 數書九章?), from 1247, written by Qin Jiushao. It has absolutely nothing to do with the Zetian character 〇, from five-six centuries before, that meant star. All Zetian characters fell out of use, shortly after the end of Wu Zetian's reign, in 705. The Zetian character 〇, would thus have been pretty much long forgotten, by 1247, and there is no reason to think that 〇 as zero, replacing □, is anything other than independently invented, and completely unconnected to the Zeitan character. Thus being a completely separate/different character. The only thing they have in common, is that they look the same. Nor is there any indication that the use of 〇 for zero, was an influence from Arabic numerals. Especially as it is only the West Arabic numeral that is circle-shaped, with the East Arabic (and also Indian) being a mere dot.

"0" in the time and calendar values of a digital clock

"0" is the first hour value, the first minute and the second who are represented by "00" in the digital clocks. Its 100 abbreviated years are represented by numbers from "00" to "99". Its adjustment will must be done secularly, except in multiple secular years of 400.

@179.98.235.119 I'm not sure what you're saying. Do you want us to add this to the article, or are you treating the talk page like a forum? —Panamitsu (talk) 10:56, 28 October 2023 (UTC)

positional number system

So imagine you were a reader wanting to understand the use of 0 in positional number systems. You get some information about this in the lead section, but if you head down to the section titled "Mathematics" all you get is two mushy sentences (preceded by a sentence telling you that this usage is not what the section is about). The history section does have a lot about the history of its use in positional systems, but that's mixed in with its other uses and split up by culture and era. I'm mildly inclined to create a section with a title like "In positional number systems" under "Mathematics" with a main article link to Positional number system; thoughts? --JBL (talk) 22:02, 24 November 2023 (UTC)

I say go for it. We can discuss it from a historical perspective in "History" and a modern one (e.g., how it works for any radix) in "Mathematics". XOR'easter (talk) 19:09, 25 November 2023 (UTC)

Ok I'll give it a go in the next few days (please ping if this turns into a lie). --JBL (talk) 23:39, 25 November 2023 (UTC)

I did a thing. (Unfortunately that thing did not involve digging up appropriate references for the short summary :/.) I think the lead section is quite good and the history is not my expertise but also seems solid; the prose in the mathematics section could use work (as well as separating out the ideas of 0 as smallest counting number from 0 as additive identity, which both have generalizations that are discussed but are really independent properties), I'll see what I can do with it next. --JBL (talk) 18:32, 27 November 2023 (UTC)

Semi-protected edit request on 7 March 2024

Under heading "Elementary algebra", I propose expanding the first sentence to read: The number 0 is the smallest nonnegative integer and also the largest nonpositive integer.

(addition: " and the largest nonpositive integer") Ciabaros (talk) 01:50, 7 March 2024 (UTC)
