It says that 2N+1 where N is natural number will define the set of natural odd numbers. Correct me if I'm wrong: I think the definition will miss 1: if 2N+1 = 1 then N=0, so the only way to get 1 is to make N=0, which is not a natural number 99.235.179.60 (talk) 14:52, 5 September 2015 (UTC)Dimmy[reply]

There are two common ways to define the Natural numbers; here we need the one that includes 0. --84.165.130.90 (talk) 09:25, 21 January 2017 (UTC)[reply]

I think this page needs help[change source]

The grammar is questionable, but I believe that should be fixed after the more conspicuous problems are cleared.Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

Are {} brackets supposed to be used in this way?Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

Is the ……… necessary after the sequence of numbers?Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

"And then you add all the number up if its over 1,000 its odd if under 1,000 its even."—This, for obvious reasons, should be fixed, but I don't understand it factually. What does it mean?Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

"Can only odd numbers be prime? What about considering irrational and fraction numbers or decimal approximations of each of these? Does it matters where one rounds the answer to?"—Why is this here? It looks like something from a school worksheet.Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

"On the other hand, an odd number, when divided by two, will result in a fraction."—This has already been said.Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

"(..., −3, −2, −1, 0, 1, 2, 3, ...)" —If {} are used for sequences, shouldn't they be here? Quinnov (talk) 07:16, 16 April 2018 (UTC)[reply]

Is is correct to say one "does not leave a remainder 1"?[change source]

The article says, "One is the first odd positive number but it does not leave a remainder 1" (referring to dividing by 2). But doesn't 1 ÷ 2 = 0, with remainder 1? FF9 (talk) 11:08, 12 March 2021 (UTC)[reply]

@FF9 A year-ish late, but I have corrected the mistake. You are correct, 1 % 2 is 1. — *Fehufangą ♮ ✉ Talk page 09:36, 20 July 2022 (UTC)[reply]
