1 (one) is the natural number following 0 and preceding 2. It represents a single entity. One is sometimes referred to as unityUnity has several meanings: In mathematics, unity refers to the number one . This also extends to electrical engineering, particularly to audio (see unity gain). Expressed in decibels, unity is 0dB. Unity is the name of the belief system held by the membe, and unitThe word unit means any of several things: One, the first natural number. The natural or usual or smallest measure of something, of which there are multiples and of which there may be fractions. In most physical contexts, for example science and engineeri is sometimes used as an adjective in this sense. (For example, a line segmentIn mathematics, a line segment is a part of a line that is bounded by two end points. See also interval (mathematics). When the end points both lie on a circle, a line segment is called a chord. When they are both vertices of a polygon, it is an edge if t of unit length is a line segment of length 1.)

1 Evolution of the glyph
The glyph we use today in the Western world to represent the number 1, a vertical line, often with a little serif at the top and sometimes a short horizontal line at the bottom, traces its roots back to the Brahmin Indians, who wrote 1 as a horizontal line (in ChineseWhen used as an adjective, Chinese refers to anything that originates from China, e. Chinese cuisine. When the word is used as a noun, it means one of the following: the Chinese language, either in general or specifically Chinese written language, Chinese today this is the way it is written). 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 simile with the Roman numeral 1.
