Traditional development In elementary school teaching, integers are often intuitively defined as the union of the (positive) natural numbers, zero, and the negations of the natural numbers. This can be formalized as follows. First construct the set of natural numbers according to the Peano axioms, call this $${\displaystyle … See more An integer is the number zero (0), a positive natural number (1, 2, 3, etc.) or a negative integer with a minus sign (−1, −2, −3, etc.). The negative numbers are the additive inverses of the corresponding positive numbers. … See more Like the natural numbers, $${\displaystyle \mathbb {Z} }$$ is closed under the operations of addition and multiplication, that is, the sum and product of any two integers is an … See more An integer is often a primitive data type in computer languages. However, integer data types can only represent a subset of all integers, since practical computers are of finite capacity. … See more 1. ^ More precisely, each system is embedded in the next, isomorphically mapped to a subset. The commonly-assumed set-theoretic containment may be obtained by constructing the reals, discarding any earlier constructions, and defining the other … See more The word integer comes from the Latin integer meaning "whole" or (literally) "untouched", from in ("not") plus tangere ("to touch"). " See more $${\displaystyle \mathbb {Z} }$$ is a totally ordered set without upper or lower bound. The ordering of $${\displaystyle \mathbb {Z} }$$ is … See more The cardinality of the set of integers is equal to ℵ0 (aleph-null). This is readily demonstrated by the construction of a bijection, … See more
