the former title of this page "111 (mathematics)" was lousy, but this has a problem: in the UK we say "One hundred and eleven". straw poll -- what do people say in other coutnries? -- Tarquin 16:43 Apr 24, 2003 (UTC)

111 is understood however you say it, so I think "111 (mathematics)" was best. Jacquerie27

The articles about numbers are not only mathematical. They also talk about the cultural denotations, historical appearances and other uses of the number. (see the examples one, two, etc.) Unless we change the titles to 1 (the number), 2 (the number), I can't think of another neutral appropriate subject category. GUllman

"The articles about numbers are not only mathematical." -- Yes, but this page was created to write about the mathematics of 111, which is why it was called "111 (mathematics)". 111 is a number used all over the world: "One hundred eleven" isn't, and it isn't even used all over the English-speaking world. Jacquerie27

The articles about smaller numbers are both mathematical and cultural. Who's to say that someone won't add cultural facts to this article, or other articles over one hundred. Sometimes the cultural uses of a number are related to its mathematics, so it doesn't make sense to create separate articles. According to dictionaries, both "one hundred and one" and "one hundred one" are acceptable, even in the U.S., so I don't have a problem with using the former as the pattern for number articles. GUllman

• All triplets in all bases are multiples of 111 in that base, therefore 111 is the only triplet that can ever be prime. It is not prime in base ten, but is prime in these bases 2 through 100: 2, 3, 5, 6, 8, 12, 14, 15, 17, 20, 21, 24, 27, 33, 38, 41, 50, 54, 57, 59, 62, 66, 69, 71, 75, 77, 78, 80, 89, 90, and 99. 111 is also prime in base 111.

What is this? The property of being a prime number has nothing to do with the base used to represent the number! Perhaps the writer was thinking of something else. -- RTC 18:03 Apr 24, 2003 (UTC)

"111 in that base", i.e. 1 x base^2 + 1 x base^1 + 1, is the important thing. 111 in base 2 = 7 in base 10 and is a prime number. But I'll re-write it to make it clear. Jacquerie27

OK, thats the confusion. I did think something important was being pointed out, just was completely confused by the words. Unfortunately the improved version still seems to take me a few reads before I catch what is being described, but I've got it now. Maybe I'll try a minor rewording myself later if I figure out what seems to trip me up. -- RTC 07:01 Apr 28, 2003 (UTC)

I'd argue for the delection or relocation of this entire paragraph, for the primary reason that this article is titles "One hundred eleven," not "111." "111" is not explicitly base ten, but "one hundred eleven" is. At least, that's what I was led to understand when I learned the new math... :) - Seth Ilys 18:04, 31 Dec 2003 (UTC)

I think that paragraph was written when the article was titled 111 (the number). If you want to include trivia about the numbers as a sequence of digits, or the digits in another base, then perhaps all of these articles should be titled 111 (number). That would also solve the American/British differences in spelling the numbers over 100 in base ten. GUllman 19:02, 31 Dec 2003 (UTC)

Please keep the squares as simple markup. tables or TeX not suitable here. -- Tarquin 08:22 May 7, 2003 (UTC)

Please note that it is technically incorrect to use the word "and" by itself when saying or spelling out a number. "One hundred and one" is just as wrong as "ninety and nine". Denelson83 00:17, 16 Dec 2003 (UTC)

One hundred eleven makes no sense in British English. The original author uses one hundred and eleven, so that's where the page should be. Angela. 01:14, 16 Dec 2003 (UTC)

I've read a mathematical puzzle that asked, "If you spelled out the counting numbers, what is the first number that would have the letter 'a'? Answer: 'one thousand' (it was an American book) GUllman 01:19, 19 Dec 2003 (UTC)

Several months ago (conversation above) I conceded that numbers over 100 should include the word 'and' since Jacquerie27 complained. Now that we have proponents on both sides, we should follow Wikipedia convention to defer to the article that first set the precedent. ... In other words, don't use the word 'and' in the title, but both forms should be mentioned in the first sentence of the article. GUllman 21:56, 22 Dec 2003 (UTC)

Which article did set the precedent? This one was not originally at one hundred eleven and if you want to use this article as the precedent, you would have to use the "and" as the original author of this article wanted the "and". Angela. 01:08, Jan 7, 2004 (UTC)
As you can see from the top of this discussion, this was the first article over 100, and it was originally titled "111 (mathematics)". Although some wanted to keep that title, majority wanted to remove "(mathematics)" to allow cultural aspects. Even before the change, Jacquerie27 noted the difference between British and American spelling, but someone started changing them to the American spelling before it was settled. GUllman 18:45, 7 Jan 2004 (UTC)
P.S.You may have seen the "111 (mathematics)" link on List of numbers was first changed to "one hundred and eleven", but it was actually [[111 (mathematics)|one hundred and eleven]]. The article itself was first moved to one hundred eleven, and soon after to one hundred and eleven (and recently back again). GUllman 23:53, 7 Jan 2004 (UTC)

"And" should not be used in writing integers. "And" should be used in place of a decimal point when writing mixed numbers. For instance, one hundred and eleven thousandths is 100.011, whereas one hundred eleven thousandths is 0.111. --Ryan_Cable 08:47, 7 Jan 2004 (UTC)

All British English speakers say "and" between 100s and 10s. AFAIK it's only in the US that the "and" is dropped. -- Tarquin 18:50, 7 Jan 2004 (UTC)
So how do they say mixed numbers such as 100.011? --Ryan_Cable 03:07, 8 Jan 2004 (UTC)
It's not just the UK. It's Australia too, and it really hurts my ears/eyes seeing things like "one hundred eleven". If you're UK/Australian, you say "one hundred point zero one one"... Dysprosia 09:30, 10 Feb 2004 (UTC)

--- CRICKET Could someone (Australian?) please elaborate on the meaning of the last paragraph of the cricket sense: -->When any aussie rules scores are G.B = 111 points, and the radio call is on 3AW, the game call team read the score in extravegent voices, led by Rex Hunt, followed by; "LORD NELSON!"<-- 11Jul08 —Preceding unsigned comment added by Peter Kidson (talkcontribs) 12:08, 11 July 2008 (UTC)

## Magic squares

I believe Magic squares require the diagonal to also add up to the magic number, so the squares in this article do not qualify. Is there a term for squares in which the rows and columns but not diagonals add up toth e same number? --S Philbrick(Talk) 14:56, 28 March 2017 (UTC)
