The Archaic Sumerian numerals for 1 and 60 both consisted of horizontal semi-circular symbols. By c.2350 BCE, the older Sumerian curviform numerals were replaced with cuneiform symbo...
Mathematically, the number 1 has unique properties and significance. In normal arithmetic (algebra), the number 1 is the first natural number after 0 (zero) and can be used to make up all other integers (e.g., 1 = 1 {\displaystyle 1=1} ; 2 = 1 + 1 {\displaystyle 2=1+1} ; 3 = 1 + 1 + 1 {\displaystyle 3=1+1+1} etc.).The product of 0 numbers (the empt...
In digital technology, data is represented by binary code, i.e., a base-2 numeral system with numbers represented by a sequence of 1s and 0s. Digitised data is represented in physical devices, such as computers, as pulses of electricity through switching devices such as transistors or logic gates where "1" represents the value for "on". As such, th...

Philo of Alexandria(20 BC – AD 50) regarded the number one as God's number, and the basis for all numbers ("De Allegoriis Legum", ii.12 [i.66]). The Neopythagorean philosopher Nicomachus of Gerasa affirmed that one is not a ...
0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 has the result 0, and consequently, division ...
In mathematics. Six is the smallest positive integer which is neither a square number nor a prime number. It is the second smallest composite number after four, equal to the sum and the product of its three proper divisors ( 1, 2 and 3 ). [1] As such, 6 is the only number that is both the sum and product of three consecutive positive numbers.
