		A natural number that is greater than one and is not a prime is called a composite number.
		Prime numbers are of fundamental importance in number theory.
		The prime number theorem says that the proportion of primes less than x is asymptotic to 1/ln x (in other words, as x gets very large, the likelihood that a number less than x is prime is inversely proportional to the number of digits in x).

		Two is the base of the simplest numeral system in which natural numbers can be written concisely, being the length of the number a logarithm of the value of the number (whereas in base 1 the length of the number is the value of the number itself); the binary system is used in computers.
		Taking the square root of a number is such a common mathematical operation, that the spot on the root sign where the exponent would normally be written for cubic roots and other such roots, is left blank for square roots, as it is considered tacit.
		It was also the number of the car which Dale Earnhardt drove to the first of his seven season championships in 1980.

	Prime number - WikiLeasing.com
		TTe study of prime numbers is part of number theory, the branch of mathematics which encompasses the study of natural numbers.
		For example, numbers whose digits dorm a palindromic sequence are called palindromic primes, and a prime number is called a truncatable prime if successively removing the first digit at the left or the right yields only new prime numbers.
		For a long time, number theory in general, and the study of prime numbers in particular, was seen as the canonical example of pure mathematics, with no applications outside of the self-interest of studying the topic.

		The study of prime numbers is part of number theory, the branch of mathematics which encompasses the study of natural numbers.
		For a long time, prime numbers were thought as having no possible application outside of number theory; this changed in the 1970s when the concepts of public-key cryptography were invented, in which prime numbers formed the basis of the first algorithms such as the RSA cryptosystem or the Diffie-Hellman key-exchange algorithm.
		For example, numbers whose digits form a palindromic sequence are called palindromic primes, and a prime number is called a truncatable prime if successively removing the first digit at the left or the right yields only new prime numbers.

		In mathematics, a prime number (or a prime) is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself.
		Until the 19th century most mathematicians considered the number 1 a prime, and there is still a large body of mathematical work that is still valid despite labelling 1 a prime, such as the work of Stern and Zeisel.

	Prime number - ExampleProblems.com
		Suppose you have a finite number of primes.
		By definition a composite number is a non-prime number with at least one positive factor other than 1 and itself.
		Thus a contradiction occurs, and for any natural number A which is greater than 1, there exists a prime divisor for A. This previous argument explains why the product of m primes + 1 must be divisible by some prime not in the finite set of primes.

	Arguments for and against the primality of 1
		To make a numerical representation where place value x (with the place value of the least significant digit being numbered either 0 or 1) is the xth prime, you have to accept 1 as a prime and assign it to the least significant digit place value.
		For a prime number p, there is no solution to the equation nq = p, where q is another prime number and n is any other positive integer; this is to say, no prime is the product of another prime and an integer.
		To accept that 2 is an untouchable number not of the form p + 1 requires us to accept that 1 is not a prime number, which is precisely what the argument was supposed to do in the first place.
