This article describes cardinal numbers in mathematics For cardinals in linguistics see Names of numbers in English. In Set theory, an ordinal number, or just ordinal, is the Order type of a Well-ordered set. A numeral system (or system of numeration) is a Mathematical notation for representing numbers of a given set by symbols in a consistent manner In Mathematics, factorization ( also factorisation in British English) or factoring is the decomposition of an object (for In Mathematics, a divisor of an Integer n, also called a factor of n, is an integer which evenly divides n without Roman numerals are a Numeral system originating in ancient Rome, adapted from Etruscan numerals. The binary numeral system, or base-2 number system, is a Numeral system that represents numeric values using two symbols usually 0 and 1. The octal Numeral system, or oct for short is the base -8 number system and uses the digits 0 to 7 The duodecimal system (also known as base -12 or dozenal) is a Numeral system using twelve as its base. In Mathematics and Computer science, hexadecimal (also base -, hexa, or hex) is a Numeral system with a In Mathematics, a square number, sometimes also called a Perfect square, is an Integer that can be written as the square of some other It is also the sum of three squares, 50 = 32 + 42 + 52. It is a Harshad number. A Harshad number, or Niven number, is an Integer that is divisible by the sum of its digits in a given number base.
There is no solution to the equation φ(x) = 50, making 50 a nontotient. In Number theory, the totient \varphi(n of a Positive integer n is defined to be the number of positive integers less than or equal to In Number theory, a nontotient is a positive integer n which is not in the range of Euler's totient function φ that is for which φ( Nor is there a solution to the equation x - φ(x) = 50, making 50 a noncototient. A noncototient is a positive integer n that can not be expressed as the difference between a positive integer m and the number of Coprime integers below
The aliquot sum of 50 is 43 and its aliquot sequence is (50,43,1,0). In Mathematics, and specifically in Number theory, a divisor function is an Arithmetical function related to the Divisors of an Integer 43 ( forty-three) is the Natural number following 42 and preceding 44. In Mathematics, an aliquot sequence is a recursive sequence in which each term is the sum of the Proper divisors of the previous term Fifty is itself the aliquot sum of 40 and 94. 40 ( forty) is the Natural number following 39 and preceding 41. 94 ( ninety-four) is the Natural number following 93 and preceding 95.
