Wikijunior talk:Numbers from 1 to 20/0

Should zero be included in a book titled "Numbers from 1 to 20"?

Its clearly not between 1 and 20.

The title of the book is actually "Numbers from 1 to 20/0" which includes zero.

 * I agree this page should be deleted, as the book title is actually "Numbers from 1 to 20" which does not include zero. Recent Runes (discuss • contribs) 16:47, 29 August 2011 (UTC)


 * Why does the title of the book have "/0" tacked on the end of it? --Pi zero (discuss • contribs) 20:25, 29 August 2011 (UTC)


 * I've only just realised myself - it has /0 tacked on the end because that's the page location book/page. I still think it's useful to have the concept of zero on here though especially as the concept is more recent than that of the other numbers.--ЗAНИA [[Image:Flag_of_Italy.svg|15px]]talk 20:34, 29 August 2011 (UTC)


 * I suppose you could argue that the numbers 10 and 20 contain the figure 0, so zero is required to understand numbers greater than 9. I imagine the target age for this book is towards the lower end of the general Wikijunior audience, but I don't know myself how numbers are actually taught in real schools. Perhaps most children are taught even larger numbers before being formally introduced to the concept of zero. Recent Runes (discuss • contribs) 20:48, 29 August 2011 (UTC)


 * Historically, I believe, the use of a placeholder symbol in numeric notation (like the digit "0" in "10" and "20") predated the perception of zero as a number by numerous centuries; the number zero is an advanced concept. This has also manifested in the past half century as a feud between mathematicians who say zero is not a natural number and computer scientists who say it is.  (Afaik the feud continues, though one imagines the computer people are slowly winning through cultural dominance.)  --Pi zero (discuss • contribs) 16:29, 30 August 2011 (UTC)
