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.

Number One Spot

"Number One Spot" is the second single from rapper Ludacris' 2004 album The Red Light District. The song heavily samples "Soul Bossa Nova" by Quincy Jones, which was used as the theme in the Austin Powers film series; Austin Powers references play major parts in "Number One Spot" and its video.

In the song's first verse, Ludacris says, "Respected highly, hi, Mr. O'Reilly/Hope all is well, kiss the plaintiff and the wifey." This line is a response to commentator Bill O'Reilly's criticism of Pepsi for featuring Ludacris in a 2002 commercial; it is a reference to a 2004 sexual harassment lawsuit brought against O'Reilly by a former employee.

The song reached #19 on the US Billboard Hot 100 chart and #30 in UK. "Number One Spot" was nominated for Best Rap Solo Performance at the Grammy Awards of 2006, but it lost to Kanye West's "Gold Digger".

A remix to the song features Kardinal Offishall.

Music video

The music video features spoofs of scenes from the Austin Powers films, with Ludacris taking the roles of Austin Powers, Fat Bastard, Goldmember and Dr. Evil. The video also features LisaRaye and Verne Troyer, who plays Mini-Me in the film franchise. Quincy Jones and Slick Rick also make appearances in the music video. The subsequent single entitled "The Potion" was the conclusion to the music video (lasting approximately 45 seconds). The video won the MTV Video Music Award for Best Rap Video in 2005.

Number

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.

In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.
