Wikipedia About One

1 (one) is a number, 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.

Mathematics

Mathematically, 1 is

  • in arithmetic (algebra) and calculus, the natural number that follows 0 and precedes 2, the multiplicative identity of the integers, real numbers and complex numbers;
  • more generally, in abstract algebra, the multiplicative identity ("unity"), usually of a ring.

For any number x:

x·1 = 1·x = x (1 is the multiplicative identity)
x/1 = x (see division)
x1 = x, 1x = 1, and for nonzero x, x0 = 1 (see exponentiation)

Using ordinary addition, we have 1 + 1 = 2.

One cannot be used as the base of a positional numeral system; sometimes tallying is referred to as "base 1", since only one mark (the tally) is needed, but this is not a positional notation.

The logarithms base 1 are undefined, since the function 1x always equals 1 and so has no unique inverse.

In the real number system, 1 can be represented in two ways as a recurring decimal: as 1.000... and as 0.999... (q.v.).

Formalizations of the natural numbers have their own representations of 1:

  • in the Peano axioms, 1 is the successor of 0;
  • in Principia Mathematica, 1 is defined as the set of all singletons (sets with one element);
  • the Von Neumann representation of natural numbers, 1 is defined as the set {0}.

In a multiplicative group or monoid, the identity element is sometimes denoted "1", but "e" (from the German Einheit, unity) is more traditional. However, "1" is especially common for the multiplicative identity of a ring, i.e. when an addition and "0" are also present. When such a ring has characteristic n not equal to 0, the element called 1 has the property that n1 = 1n = 0 (where this 0 is the additive identity of the ring). Important examples are general fields.

In Boolean algebra, 1 corresponds to true.

One is its own factorial, and its own square and cube (and so on, as 1 × 1 × ... × 1 = 1). One is the first figurate number of every kind, such as triangular number, pentagonal number and centered hexagonal number to name just a few.

Because of the multiplicative identity, if f(x) is a multiplicative function, then f(1) must equal 1.

It is also the first and second numbers in the Fibonacci sequence, and is the first number in many mathematical sequences. As a matter of convention, Sloane's early Handbook of Integer Sequences added an initial 1 to any sequence that didn't already have it, and considered these initial 1's in its lexicographic ordering. Sloane's later Encyclopedia of Integer Sequences and its Web counterpart, the On-Line Encyclopedia of Integer Sequences, ignore initial ones in their lexicographic ordering of sequences, because such initial ones often correspond to trivial cases.
