This draft's references do not show that the subject meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that:

provide significant coverage: discuss the subject in detail, not just brief mentions or routine announcements;
are reliable: from reputable outlets with editorial oversight;
are independent: not connected to the subject, such as interviews, press releases, the subject's own website, or sponsored content.

Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia.

If you would like to continue working on the submission, click on the "Edit" tab at the top of the window.
If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.
If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.
Please do not remove reviewer comments or this notice until the submission is accepted.

Where to get help

If you need help editing or submitting your draft, please ask us a question at the AfC Help Desk or get live help from experienced editors. These venues are only for help with editing and the submission process, not to get reviews.
If you need feedback on your draft, or if the review is taking a lot of time, you can try asking for help on the talk page of a relevant WikiProject. Some WikiProjects are more active than others so a speedy reply is not guaranteed.

This draft reads like an essay or opinion piece. Wikipedia is not a place for original research or personal opinions. The draft should:

summarize secondary sources: do not offer your own analysis or arguments;
be written from a neutral point of view: represent the subject without bias, avoiding praise, criticism, or persuasive or promotional language;
not contain original research: do not include new theories, unpublished ideas, or personal experiences.

Instead, only summarize in your own words a range of independent, reliable, published sources that discuss the subject.

This draft appears to be a dictionary definition. Wikipedia is not a dictionary and we do not accept articles that are simply definitions of words, acronyms, or slang.

To improve the draft it must expand on the subject, such as discussing its history, cultural significance, or impact rather than just defining the word;

Comment: Per comment by User:Hurricane Wind and Fire, needs a properties section on a par with -2. Stuartyeates (talk) 23:15, 13 June 2026 (UTC)

Comment: Still largely just a dictionary definition. Expand onto the properties section to a point where it is similar to the properties section in -2 and it will be ready for acceptance. 🌀Hurricane Wind and Fire, why did you decline my draft? (talk) (contribs)🔥 03:41, 12 June 2026 (UTC)

Comment: If you want the draft to be like -2, then please include citations so this is not a dictionary entry GGOTCC 21:07, 1 November 2025 (UTC)

In mathematics, negative three or minus three is an negative integer three units from the origin, denoted as −3 or ⁻3. It is the additive inverse of 3, positioned between −4 and −2. It is the second largest negative odd number.

Properties

Negative three is a quadratic residue modulo 4.^[1]
Negative three is the first, and smallest negated heegner number. only nine negative numbers have this property: −3, −4, −7, −8, −11, −19, −43, −67, −163.^[2]
Negative three is the only negative integer whose Möbius function value appears as a fixed point of the map in the sequence 𝜇(𝑛) ∈ {−1,0,1}.^[3]

Divisors of negative three

The divisors of the number negative three, including negative divisors, are identical to those of two: 1, 3, −1 −3.^[4] Since its only divisors are ±1 and ±3, negative three is considered an irreducible element, which is the equivalent of a prime number for negative integers.^[5]

Square root of negative three

The square root of negative three produces both quadratic field, and cyclotomic field.^[6]

In the quadratic field $\mathbb {Q} ({\sqrt {-3}})$ , negative three is its fundamental discriminant, and the ring of integers in this field is the lattice of Eisenstein integers.^[7]

{\mathit {Z}}[\omega ],\omega ={\frac {-1+{\sqrt {-3}}}{2}}

which forms a perfect hexagonal (triangular) lattice in the plane.^[7]

The quadratic field also has class number 1, meaning it behaves better as the integers for factoring.^[8]

In the cyclotomic field $\mathbb {Q} (\zeta _{3})$ , the discriminant of the field is −3,^[7] meaning three is the only rational prime that becomes ramified,^[9]^[10] and the ramification index is exactly two.
