The number two has many properties in [[mathematics]].<ref>Wells, D. ''[[The Penguin Dictionary of Curious and Interesting Numbers]]'' London: Penguin Group. (1987): 41–44</ref> An [[integer]] is called ''[[Parity (mathematics)|even]]'' if it is divisible by 2. For integers written in a numeral system based on an even number, such as [[decimal]] and [[hexadecimal]], divisibility by 2 is easily tested by merely looking at the last digit. If it is even, then the whole number is even. In particular, when written in the decimal system, all multiples of 2 will end in 0, 2, 4, 6, or 8.

Two is the only number ''x'' such that the sum of the reciprocals of the powers of ''x'' equals itself. In symbols
 
:<math>\sum_{k=0}^{\infin}\frac {1}{2^k}=1+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+\cdots=2.</math>
 
This comes from the fact that:
 
:<math>\sum_{k=0}^\infin \frac {1}{n^k}=1+\frac{1}{n-1} \quad\mbox{for all} \quad n\in\mathbb R > 1.</math>
 
[[Power of two|Powers of two]] are central to the concept of [[Mersenne prime]]s, and important to [[computer science]]. Two is the first Mersenne prime exponent.
 
Taking the [[square root]] of a number is such a common mathematical operation, that the spot on the root sign where the exponent would normally be written for cubic roots and other such roots, is left blank for square roots, as it is considered tacit.
 
The [[square root of 2]] was the first known [[irrational number]].
 
The smallest [[field (mathematics)|field]] has two elements.
 
In the [[set theory|set-theoretical]] construction of the natural numbers, 2 is identified with the set <math>\{\{\emptyset\},\emptyset\}</math>. This latter set is important in [[category theory]]: it is a [[subobject classifier]] in the category of sets.
 
Two is a [[primorials|primorial]], as well as its own [[factorial]]. Two often occurs in numerical sequences, such as the [[Fibonacci numbers|Fibonacci number]] sequence, but not quite as often as one does. Two is also a [[Motzkin number]], a [[Bell number]], an [[Harshad number|all-Harshad number]], a [[meandric number]],  a [[semi-meandric number]], and an [[open meandric number]].
 
Two is the number of [[Eight queens puzzle|n-Queens Problem]] solutions for n = 4. With one exception, all known solutions to [[Znám's problem]] start with 2.
 
Two also has the unique property such that
 
:<math>\sum_{k=0}^{n-1} 2^k = 2^{n} - 1</math>
 
and also
 
:<math>\sum_{k=a}^{n-1} 2^k = 2^n - \sum_{k=0}^{a-1} 2^k - 1</math>
for ''a'' not equal to zero
 
The number of domino tilings of a 2×2 [[checkerboard]] is 2.
 
For any polyhedron homeomorphic to a sphere, the [[Euler characteristic]] is

==Evolution of the glyph==
[[Image:Evolution2glyph.png|x50px|right]]
The [[glyph]] used in the modern Western world to represent the number 2 traces its roots back to the Brahmin Indians, who wrote "2" as two horizontal lines. The modern [[Chinese written language|Chinese]] and [[Japanese writing system|Japanese]] languages still use this method. The [[Gupta script|Gupta]] rotated the two lines 45 degrees, making them diagonal, and sometimes also made the top line shorter and made its bottom end curve towards the center of the bottom line. Apparently for speed, the [[Nagari]] started making the top line more like a curve and connecting to the bottom line. The Ghubar Arabs made the bottom line completely vertical, and now the glyph looks like a dotless closing question mark. Restoring the bottom line to its original horizontal position, but keeping the top line as a curve that connects to the bottom line leads to our modern glyph.<ref>Georges Ifrah, ''The Universal History of Numbers: From Prehistory to the Invention of the Computer'' transl. David Bellos et al. London: The Harvill Press (1998): 393, Fig. 24.62</ref>

==In religion==
 
The number 2 is important in [[Judaism]], with one of the earliest reference being that God ordered Noah to put two of every [[unclean animals|unclean animal]] (Gen. 7:2) in his ark (see [[Noah's Ark]]). Later on, the [[Ten Commandments]] were given in the form of two tablets. The number also has ceremonial importance, such as the two candles that are traditionally kindled to usher in the [[Shabbat]], recalling the two different ways Shabbat is referred to in the two times the [[Ten Commandments]] are recorded in the [[Torah]]. These two expressions are known in [[Hebrew language|Hebrew]] as שמור וזכור ("guard" and "remember"), as in "Guard the Shabbat day to sanctify it" (Deut. 5:12) and "Remember the Shabbat day to sanctify it" (Ex. 20:8). Two [[challah]]s (''lechem mishnah'') are placed on the table for each [[Shabbat]] meal and a blessing made over them, to commemorate the double portion of [[manna]] which fell in the [[The Exodus|desert]] every Friday to cover that day's meals and the Shabbat meals
 
In [[Halakha|Jewish law]], the testimony of two witnesses are required to verify and validate events, such as [[Jewish view of marriage|marriage]], divorce, and a crime that warrants [[capital punishment]]
 
"Second-Day Yom Tov" (''Yom Tov Sheini Shebegaliyot'') is a rabbinical enactment that mandates a two-day celebration for each of the one-day [[Jewish holiday|Jewish festivals]] (i.e., the first and seventh day of [[Passover]], the day of [[Shavuot]], the first day of [[Sukkot]], and the day of [[Shemini Atzeret]]) outside the land of [[Israel]].
 
==Numerological significance==
[[Image:2 playing cards.jpg|thumb|250px|The twos of all four suits in [[playing card]]s]]
 
The most common philosophical [[dichotomy]] is perhaps the one of [[Goodness and value theory|good]] and [[evil]], but there are many others. See [[dualism]] for an overview. In [[Georg Wilhelm Friedrich Hegel|Hegel]]ian [[dialectic]], the process of [[Thesis, antithesis, synthesis|synthesis]] creates two perspectives from one.
The ancient Sanskrit language (संस्कृत भाषा)  of India, does not only have a singular and dual form for nouns, as do most other languages, but instead has, a singular (1) form, a dual (2) form, and a plural (everything above 2)form, for all nouns, due to the significance of 2. It is viewed as important because of the anatomical significance of 2 (2 hands, 2 nostrils, 2 eyes, 2 legs, etc.)
 
Two (二, ''èr'') is a good [[number in Chinese culture]]. There is a Chinese saying, "good things come in pairs". It is common to use double symbols in product brandnames, e.g. double happiness, double coin, double elephants etc. [[Guangdong|Cantonese]] people like the number two because it sounds the same as the word "easy" (易) in [[Cantonese language|Cantonese]].
 
In [[Finland]], two [[candle]]s are lit on [[Independence Day (Finland)|Independence Day]]. Putting them on the windowsill invokes the symbolical meaning of division, and thus independence. {{Citation needed|date=May 2008}}
 
In pre-1972 [[Indonesian language|Indonesian]] and [[Malay language|Malay]] orthography, ''2'' was shorthand for the [[reduplication]] that forms plurals: ''orang'' "person", ''orang-orang'' or ''orang2'' "people". {{Citation needed|date=May 2008}}
 
In [[Astrology]], [[Taurus (constellation)|Taurus]] is the second [[astrological sign|sign]] of the [[Zodiac]].
 
==In sports==
[[Football]]:
*In [[American football]], a safety has a two-point value. Also, a two-point conversion is a point after touchdown (PAT) attempt where the ball crosses the goal line via run or pass. (In [[six-man football]], however, the traditional PAT kick is worth two points, whereas a PAT via pass or run is only one point.)
*In [[Association football]], the scoring of two goals by one individual in a single match is referred to as a brace.
**The successor of a ''brace'' is the "'''[[hat-trick]]'''", three goals scored by one player.
 
[[Basketball]]:
* In standard basketball, the value of any made shot taken from inside the [[Three-point field goal|three-point arc]] in normal play is 2 points.
* In the half-court [[3x3 (basketball)|3x3]] variant, made shots taken from outside the "three-point" arc are worth 2 points.

After a little silence

Some other mercenaries, is followed by a large army ran up, they would like to see, what is the story behind, could have qualified to lead such a large-scale siege.

'catch Xiao Yan, the guy who has a mysterious order Gong!'
