what are integers

The integers (from the Latin integer, literally "untouched", hence "whole": the word entire comes from the same origin, but via French^[1]) are formed by the natural numbers including 0 (0, 1, 2, 3, ...) together with the negatives of the non-zero natural numbers (−1, −2, −3, ...). Viewed as a subset of the real numbers, they are numbers that can be written without a fractional or decimal component, and fall within the set {..., −2, −1, 0, 1, 2, ...}. For example, 21, 4, and −2048 are integers; 9.75, 5½, and 14% are not integers.

The set of all integers is often denoted by a boldface Z (or blackboard bold , Unicode U+2124 ℤ), which stands for Zahlen (German for numbers, pronounced [ˈtsaːlən]).^[2] The set is the finite set of integers modulo n (for example, ).

The integers (with addition as operation) form the smallest group containing the additive monoid of the natural numbers. Like the natural numbers, the integers form a countably infinite set.

In algebraic number theory, these commonly understood integers, embedded in the field of rational numbers, are referred to as rational integers to distinguish them from the more broadly defined algebraic integers (but with "rational" meaning "quotient of integers", this attempt at precision suffers from circularity).

plzzzzzzzzzzzzz thumb's up

 Integers include whole numbers and theirs opposites.The opposite of whole number is the negative of that number.The number 0 is also considered an integer,but 0 is the opposite of itself.

...-4,-3,-2,-1,0,1,2,3,4...

tune kya rediff.com mese nikala hai yeh ans

Hello ! I will help you.

 Integers are all the whole numbers and their opposites. The opposite of a whole number is the negative of that number. Even though zero is the opposite of itself it is also considered an integer.

Plz thumbs up

u copied my ans.

nooooo......

 to phir mera ans same hai tere jaisa

 meine rediff.com mein se nikala hai. tere se copied nahi ki hai

u copied it

same ans. kyu nikala.....!!

 muje jo mila meine wo chap diya

chap dia?????? means

 rediff.com mein se nikala aur copy kar ke isme paste kar diy

okay ..... so mai kya karu

 Hi!

Integers are a set of numbers which include whole numbers and negative numbers.

Cheers!
