A trusted site that overcomplicates very
simple things. For example:
1 (one, also called unit, and unity) is a number and a numerical digit used to represent that number in numerals. 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. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer.1 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.
