What is Integers?
  • 4 answers

Preet Verma 5 years ago

An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not.
In Maths, integers are the numbers which can be positive, negative or zero, but cannot be a fraction. These numbers are used to perform various arithmetic operations, like addition, subtraction, multiplication and division. The examples of integers are, 1, 2, 5,8, -9, -12, etc. The symbol of integers is “Z“. In terms of sets, the set of integers includes zero, set of whole numbers, set of natural numbers (also called counting numbers) and their additive inverses (-1,-2,-3,-4,-5,..). Integers are the subset of real numbers.  Example of integers: -100,-12,-1, 0, 2, 1000, 989 etc… As a set, it can be represented as follows: Z= {……-8,-7,-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8,……}
