1 (number)

1 (one; /ˈwʌn/ or UK /ˈwɒn/, also called unit, unity, and (multiplicative) identity), is a number, a numeral, and the name of the glyph representing that number. It represents a single entity, the unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1.

As a number

One, sometimes referred to as unity, is the integer before two and after zero. One is the first non-zero number in the natural numbers as well as the first odd number in the natural numbers.

Any number multiplied by one is that number, as one is the identity for multiplication. As a result, one is its own factorial, its own square, its own cube, and so on. One is also the result of the empty product, as any number multiplied by one is itself. It is also the only natural number that is neither composite nor prime with respect to division, but instead considered a unit.

As a digit

The glyph used today in the Western world to represent the number 1, a vertical line, often with a serif at the top and sometimes a short horizontal line at the bottom, traces its roots back to the Indians, who wrote 1 as a horizontal line, much like the Chinese character 一. The Gupta wrote it as a curved line, and the Nagari sometimes added a small circle on the left (rotated a quarter turn to the right, this 9-look-alike became the present day numeral 1 in the Gujarati and Punjabi scripts). The Nepali also rotated it to the right but kept the circle small. This eventually became the top serif in the modern numeral, but the occasional short horizontal line at the bottom probably originates from similarity with the Roman numeral I. In some countries, the little serif at the top is sometimes extended into a long upstroke, sometimes as long as the vertical line, which can lead to confusion with the glyph for seven in other countries. Where the 1 is written with a long upstroke, the number 7 has a horizontal stroke through the vertical line.

Paris Hilton

Paris Whitney Hilton (born February 17, 1981) is an American socialite, television personality, model, actress, singer, DJ, businesswoman, and author. She is the great-granddaughter of Conrad Hilton, the founder of Hilton Hotels. Born in New York City and raised there and in Beverly Hills, California, Hilton began her modeling career as a teenager when she signed with Donald Trump's agency, Trump Model Management. Her lifestyle and rumored short-lived relationships made her a feature of entertainment news, and Hilton was proclaimed "New York's leading It girl" in 2001. In 2003, a sex tape with Hilton and her then-boyfriend Rick Salomon, later released as 1 Night in Paris, was made public. Released only three weeks before the premiere of the reality television series The Simple Life, in which she starred alongside her long-time friend Nicole Richie, the sex tape became a media sensation. The Simple Life continued for five seasons and gave both women international recognition.
