The set of all integers is often denoted by the boldface Z or blackboard bold. [ 3 ] [ 4 ] The set of natural numbers N {\displaystyle \mathbb {N} } is a subset of Z {\displaystyle \mathbb {Z} } , which in turn is a subset of the set of all rational numbers Q {\displaystyle \mathbb {Q} } , itself a subset of the real numbers R {\displaystyle ...
The set of all integers is usually denoted by Z (or Z in blackboard bold, ), which stands for Zahlen (German for "numbers"). Articles about integers are automatically sorted in numerical order. Do not set a sort key in them, unless thousands separators are used.
All integers are rational, but there are rational numbers that are not integers, such as −2/9. Real numbers (): Numbers that correspond to points along a line. They can be positive, negative, or zero. All rational numbers are real, but the converse is not true.
Z or z is the twenty-sixth and last letter of the Latin alphabet. It is used in the modern English alphabet , in the alphabets of other Western European languages, and in others worldwide. Its usual names in English are zed ( / ˈ z ɛ d / ), which is most commonly used in British English and zee ( / ˈ z iː / ), most commonly used in North ...
Given a Gaussian integer z 0, called a modulus, two Gaussian integers z 1,z 2 are congruent modulo z 0, if their difference is a multiple of z 0, that is if there exists a Gaussian integer q such that z 1 − z 2 = qz 0. In other words, two Gaussian integers are congruent modulo z 0, if their difference belongs to the ideal generated by z 0.
/, the set of all integers modulo n., the set of all p-adic integers or sometimes the set of all integers modulo n. Z, symbol for plastic section modulus, a geometric property; Z, the number 35 in base 36 and higher; z-axis, part of the Cartesian coordinate system

Consider the group of integers (under addition) and the subgroup consisting of all even integers. This is a normal subgroup, because Z {\displaystyle \mathbb {Z} } is abelian . There are only two cosets: the set of even integers and the set of odd integers, and therefore the quotient group Z / 2 Z {\displaystyle \mathbb {Z} \,/\,2\mathbb {Z ...
