Translingual Etymology Tenth century “West Arabic” variation of the Nepali form of Hindu-Arabic numerals (compare Devanagari script १ (1, “éka”)), possibly influenced by Roman numeral Ⅰ. Symbol 1 (previous 0, next 2) The cardinal number one, a single thing or unit. A digit in decimal and every other base numbering system, including binary, octal, and hexadecimal. 15 × 134 = 2010 0010 00112 (the number 35 in binary notation) 0x1000E001 (the number 268492801 in hexadecimal notation) (mathematics) The identity element with respect to multiplication in a ring. a×1 = a (computer science) Bit state corresponding to binary digit 1, or on or true. (mathematics) A Boolean or truth value corresponding to true. f : Bk → B : B = {0, 1} (mathematics) The one-point topological space, trivial ring, trivial group, a category with a single object or a (canonical) singleton. (mathematics, set theory) indicator function of a set. (phonetics) the pitch of a tone, either high or low depending on local convention; '1' is most commonly the highest or lowest pitch (but see 0) Synonyms: ˥, ˩ (phonetics, Sinosphere) tone number 1, typically identified with dark level yin ping (陰平). May simply be level ping tone (平) if the yin–yang distinction is not made.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the smallest possible difference between two distinct natural numbers. The unique mathematical properties of the number have led to its unique uses in other fields, ranging from science to sports. It commonly denotes the first, leading, or top thing in a group.
