2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures. As a word ''Two'' is most commonly a determiner used with plural countable nouns, as in ''two days'' or ''I'll take these two''. ''Two'' is a noun when it refers to the number two as in ''two plus two is four.'' Etymology of ''two'' The word ''two'' is derived from the Old English words (feminine), (neuter), and (masculine, which survives today in the form twain). The pronunciation , like that of ''who'' is due to the labialization of the vowel by the ''w'', which then disappeared before the related sound. The successive stages of pronunciation for the Old English would thus be , , , , and finally . Mathematics An integer is determined to be even if it is divisible by two.

2 BC
__NOTOC__ Year 2 BC was a common year starting on Thursday or Friday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Wednesday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Silvanus (or, less frequently, year 752 '' Ab urbe condita''). The denomination 2 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Egyptian Numerals
The system of ancient Egyptian numerals was used in Ancient Egypt from around 3000 BCE until the early first millennium CE. It was a system of numeration based on multiples of ten, often rounded off to the higher power, written in hieroglyphs. The Egyptians had no concept of a place-valued system such as the decimal system. The hieratic form of numerals stressed an exact finite series notation, ciphered one-to-one onto the Egyptian alphabet. Digits and numbers The following hieroglyphs were used to denote powers of ten: Multiples of these values were expressed by repeating the symbol as many times as needed. For instance, a stone carving from Karnak shows the number 4,622 as: Egyptian hieroglyphs could be written in both directions (and even vertically). In this example the symbols decrease in value from top to bottom and from left to right. On the original stone carving, it is right-to-left, and the signs are thus reversed. Zero and negative numbers By 1740 BCE, the Egy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babylonian Cuneiform Numerals
Assyro-Chaldean Babylonian cuneiform numerals were written in cuneiform, using a wedge-tipped reed stylus to make a mark on a soft clay tablet which would be exposed in the sun to harden to create a permanent record. The Babylonians, who were famous for their astronomical observations, as well as their calculations (aided by their invention of the abacus), used a sexagesimal (base-60) positional numeral system inherited from either the Sumerian or the Akkadian civilizations. Neither of the predecessors was a positional system (having a convention for which 'end' of the numeral represented the units). Origin This system first appeared around 2000 BC; its structure reflects the decimal lexical numerals of Semitic languages rather than Sumerian lexical numbers. However, the use of a special Sumerian sign for 60 (beside two Semitic signs for the same number) attests to a relation with the Sumerian system. Characters The Babylonian system is credited as being the first known positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Georgian Numerals
The Georgian numerals are the system of number names used in Georgian, a language spoken in the country of Georgia. The Georgian numerals from 30 to 99 are constructed using a base-20 system, similar to the scheme used in Basque, French for numbers 80 through 99, or the notion of the '' score'' in English. The symbols for numbers in modern Georgian texts are the same Arabic numerals used in English, except that the comma is used as the decimal separator, and digits in large numbers are divided into groups of three using spaces or periods (full stops). An older method for writing numerals exists in which most of letters of the Georgian alphabet (including some obsolete letters) are each assigned a numeric value.Makharoblidze (2009), p. 7 Cardinal numbers The Georgian cardinal numerals up to ten are primitives, as are the words for 20 and 100, and also "million", "billion", etc. (The word for 1000, though, is not a primitive.) Other cardinal numbers are formed from these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thai Numerals
Thai numerals ( th, เลขไทย, , ) are a set of numerals traditionally used in Thailand, although the Arabic numerals are more common due to extensive westernization of Thailand in the modern Rattanakosin period. Thai numerals follow the Hindu–Arabic numeral system commonly used in the rest of the world. In Thai language, numerals often follow the modified noun and precede a measure word, although variations to this pattern occur. Usage The Thai language lacks grammatical number. A count is usually expressed in the form of an uninflected noun followed by a number and a classifier. "Five teachers" is expressed as "teacher five person" ( th, ครูห้าคน or with the numeral included th, ครู ๕ คน.) "person" is a type of referent noun that is also used as the Thai part of speech called in English a linguistic classifier, or measure word. In Thai, counting is ''kannap'' (; ''nap'' is "to count", ''kan'' is a prefix that forms a noun from a ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maya Numerals
The Mayan numeral system was the system to represent numbers and calendar dates in the Maya civilization. It was a vigesimal (base-20) positional numeral system. The numerals are made up of three symbols; zero (a shell), one (a dot) and five (a bar). For example, thirteen is written as three dots in a horizontal row above two horizontal bars; sometimes it is also written as three vertical dots to the left of two vertical bars. With these three symbols, each of the twenty vigesimal digits could be written. Numbers after 19 were written vertically in powers of twenty. The Maya used powers of twenty, just as the Hindu–Arabic numeral system uses powers of ten. For example, thirty-three would be written as one dot, above three dots atop two bars. The first dot represents "one twenty" or "1×20", which is added to three dots and two bars, or thirteen. Therefore, (1×20) + 13 = 33. Upon reaching 202 or 400, another row is started (203 or 8000, then 204 or 160,000, and so on). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khmer Numerals
Khmer numerals are the numerals used in the Khmer language. They have been in use since at least the early 7th century, with the earliest known use being on a stele dated to AD 604 found in Prasat Bayang, near Angkor Borei, Cambodia. Numerals Having been derived from the Hindu numerals, modern Khmer numerals also represent a decimal positional notation system. It is the script with the first extant material evidence of zero as a numerical figure, dating its use back to the seventh century, two centuries before its certain use in India. Old Khmer, or Angkorian Khmer, also possessed separate symbols for the numbers 10, 20, and 100. Each multiple of 20 or 100 would require an additional stroke over the character, so the number 47 was constructed using the 20 symbol with an additional upper stroke, followed by the symbol for number 7. This inconsistency with its decimal system suggests that spoken Angkorian Khmer used a vigesimal system. As both Thai and Lao scripts ...

Armenian Numerals
The system of Armenian numerals is a historic numeral system created using the majuscules (uppercase letters) of the Armenian alphabet. There was no notation for zero in the old system, and the numeric values for individual letters were added together. The principles behind this system are the same as for the Ancient Greek numerals and Hebrew numerals. In modern Armenia, the familiar Arabic numerals are used. Armenian numerals are used more or less like Roman numerals in modern English, e.g. Գարեգին Բ. means Garegin II and Գ. գլուխ means ''Chapter III'' (as a headline). The final two letters of the Armenian alphabet, "o" (Օ) and "fe" (Ֆ), were added to the Armenian alphabet only after Arabic numerals were already in use, to facilitate transliteration of other languages. Thus, they sometimes have a numerical value assigned to them. Algorithm Numbers in the Armenian numeral system are obtained by simple addition. Armenian numerals are written left-to-right (a ...

Hebrew Numerals
The system of Hebrew numerals is a quasi-decimal alphabetic numeral system using the letters of the Hebrew alphabet. The system was adapted from that of the Greek numerals in the late 2nd century BCE. The current numeral system is also known as the ''Hebrew alphabetic numerals'' to contrast with earlier systems of writing numerals used in classical antiquity. These systems were inherited from usage in the Aramaic and Phoenician scripts, attested from c. 800 BCE in the so-called Samaria ostraca and sometimes known as ''Hebrew-Aramaic numerals'', ultimately derived from the Egyptian Hieratic numerals. The Greek system was adopted in Hellenistic Judaism and had been in use in Greece since about the 5th century BCE. In this system, there is no notation for zero, and the numeric values for individual letters are added together. Each unit (1, 2, ..., 9) is assigned a separate letter, each tens (10, 20, ..., 90) a separate letter, and the first four hundreds (100, 200, 300, 400) a s ...
