Wikipedia:WikiProject Numbers

This WikiProject is aimed at improving editing practice on articles devoted to numbers. General guideline advise is given throughout to assist in creating and improving these articles.

Objectives

General goals

Per assessment at WikiProject Mathematics and recommendations found here,

Improve existing number articles, and
Create new number articles that merit it.

For now, the Project focuses on number articles devoted to integers.

Current priorities

Tidy and improve exiting integer number articles, information which can be added and removed, as well as reorganized and converted into prose.
Methodically assign "priorities" to integer number articles (top, high, mid, and low), following a systematic approach, still to be discussed.

Discussions regarding the involvement of the Project on mathematics topics not specific to integers such as constants, irrational numbers and algebraic numbers have yet to be initiated, including involvement on main topics about numbers, and their extensions.

Structure

Articles after 10 are named, for the most part, $N (number)$ .

Navigation bars inside Number Infoboxes for number articles on integers have been added, with the following functionality:

Increments of 1 for all integer number articles between −1 and 313 (number).
Increments of 10 from 0 through 270 (number), to be made continuous with the span of consecutive articles.
Increments of 100 from 0 through 1000 (number), starting at 100.
Increments of 1000 between 1000 (number) through 9000 (number), and of 10,000 between 10,000 and 90,000.
Increments by factors of 10^x between 1 and 1,000,000,000 (i.e. 1, 10, 100, ..., 1,000,000,000, with links starting at 100,000).

Currently, there are continuous individual number articles for integers from −1 to 313 (number).

300 (number) is the first article to specifically detail information for one hundred integers in one page.
From 300 (number) to 1000 (number), articles contain information for individual integers in ranges of hundreds.
From 1000 (number) to 10,000 (number), information is grouped in ranges of thousands.
From 10,000 to 100,000, articles cover information on integers in ranges of ten thousands.
From 100,000 through 1,000,000,000, articles are grouped in ranges of increments of powers of ten, 10^x (up to 1,000,000,000).

There are also select article entries linked to individual articles within these ranges. Some articles are devoted to integers in ranges greater than 10⁹.

Regarding the status of disambiguation pages,

11 is a disambiguation page linking to 11 (number), other articles. Similarly for 12 through 99, inclusive.
100 (disambiguation) links to 100 (number page), and other articles.
101 is a disambiguation page linking to 101 (number), and other articles, as with 102 to 150, inclusive.

The next disambiguation number page is 163 (disambiguation), linking to 163 (number) and other articles.

Assessment

Following the level of priority set by WikiProject Mathematics, there are two main top-priority mathematics number articles for integers: 0 and 1. These are well-written and could soon be raised to GA status.

Relevant mathematics number articles categorized as high-priority include,

−1, 1⁄2, 2, 3, 4, 5, 6, 7, 8, 9, and 10, as well as 24 (number) and 1000.

These have all recently been improved (2022-). Relevant mid-priority articles include

11 (number) through 19 (number), as well as 20 (number), 30 (number), and 40 (number),
10,000 and 1,000,000,000, and
0.999..., with featured status.

1729 (number) is also specifically rated as mid-priority. Low-priority articles include 261 (number) and 666 (number) (as well as, 2,147,483,647).
