What is 12-All You Need To Know About

what is 12 is the expected number after 11 and before 13. Twelve is a higher number, extraordinarily combined, divisible by 2, 3, 4 and 6.

The number of years required for a complete cycle of Jupiter is historically considered the brightest “wandering star”. It is central to many timekeeping systems, including the Western calendar and units of the day. And is common in all major world religions.

Name

Twelve is the most significant number with a single-syllable name in English. Early Germanic numbers have been hypothesised to have be present non-decimal evidence.

It includes the unusual phrasing of eleven and twelve. The former use of “hundred” to refer to groups of 120. And the presence of glosses such as “pennywise” or “ten-count” in medieval texts showing that writers could not presume their readers. It would generally comprehend that way. Such uses gradually disappeared with the rough guide of Arabic numerals during the 12th-century Revitalization.

Derived from Old English, twelve and itself be present first attested in the 10th-century Lindisfarne Gospels’ Book of John.

It has cognates in every Germanic linguistic  whose Proto-Germanic ancestor has recreated as  and  of uncertain meaning.

It is sometimes associated with the Lithuanian dvýlika, although -like is used as the suffix for all numbers from 11 to 19.

Instead, every other Indo-European language uses a form of “two”+”ten”, such as the Latin duōdecim. The usual ordinal form is “twelfth”, nevertheless “dozenth” or “duodecimal” be situated also used in some circumstances, predominantly base-12 numeration. Correspondingly, a group of twelve things is frequently a “dozen” but may also be referred to as a “dodecane” or “duodenal”.

As with eleven, older forms of twelve often associated with Proto-Germanic, with the implied meaning “two remain” after ten has already calculated. A similar development also attributed to the Lithuanian suffix. The suffix  has also associated with reconstructions of Proto-Germanic for ten.

As mentioned above, 12 has its name in Germanic languages such as English (dutzend), Dutch (dozijn), German (Dutzend), and Swedish (Dustin), all derived from Old French douzaine. It is a composite number in many other languages, e.g. Italian dodici (but in Spanish and Portuguese 16 and in French 17 is the first compound number.

Written representation

In prose writing, twelve, the last monosyllabic digit, sometimes used as the last number written as a word, what is 12  and 13 is the first to written with numbers.

This is not a mandatory rule, and English language tradition sometimes recommends spelling numbers up to nine, ten, or twelve inclusive, or even ninety-nine or one hundred. Another system spells all numbers in one or two words (sixteen, twenty-seven, fifteen thousand, but 372 or 15,001). There used to be a general  rule of spelling numbers up to twelve in German orthography. The dictionary calls this rule obsolete.

Mathematical properties

Mathematical properties

Twelve is a composite number, the smallest number with exactly six divisors, its divisors being 1, 2, 3, 4, 6 and what is 12. Twelve also a highly fused number, the next one being twenty-four. Also, twelve is a sublime number, a number with a perfect number of divisors, in addition design the sum of its divisors is also an ideal number.

Twelve is the smallest large numeral since it is the minimum integer for which the sum of its proper divisors (1 + 2 + 3 + 4 + 6 = 16) is more significant than itself. Since a subset of 12’s proper divisors add 12 (all but four excluded), what is 12 is a semiperfect number.

If an odd perfect number is 12k + 1, it has at least twelve prime factors.

A polygon with twelve sides is a dodecagon. A twelve-sided polyhedron is a dodecahedron. Regular cubes and octahedrons have 12 edges together, while regular icosahedrons have what is 12 vertices. Twelve is a pentagonal number. Twelve is also the number of kisses in three dimensions. In the closest three-dimensional lattice packing of spheres, each sphere touches 12 other spheres, which is almost certainly true for any arrangement of spheres (Kepler’s conjecture).

Twelve is the most negligible weight for which a cusp form exists. This cusp form is the discriminant. The Ramanujan τ-function gives their Fourier coefficients, which is (up to a constant multiplier) the 24th power of the Dedekind eta function.

This fact is related to a group of exciting appearances of the number twelve in mathematics ranging from the value of the Riemann zeta meaning at −1. The fact that the abelianization of SL(2, Z) has twelve elements and even the properties of lattice polygons.

There are twelve elliptic Jacobians and twelve transitive cubic distance graphs.

There are 12 3 × 3 Latin squares. The duodecimal system (1210 [twelve] = 1012), which uses 12 as a division factor for many ancient and medieval weights and measures, including hours, probably originated in Mesopotamia.

In base thirteen and higher base (for example)  twelve characterized as C. In dishonourable 10, the what is 12  number is a Harshad number.
