whole numbers
Whole numbers are a set of numbers that include all positive numbers (including zero) and their corresponding negatives
Whole numbers are a set of numbers that include all positive numbers (including zero) and their corresponding negatives. They are called “whole” because they represent complete units or quantities and do not include any fractions or decimals. Whole numbers are denoted by the symbol ‘W’ and can be represented as:
W = {0, 1, 2, 3, 4, 5, …}
Some key characteristics of whole numbers are:
1. Zero (0): Zero is the smallest whole number and represents the absence of any quantity or value. It lies at the center of the number line and acts as a reference point for positive and negative numbers.
2. Counting numbers: Whole numbers include all positive counting numbers starting from 1. These numbers are used to count objects or elements in a set. For example, 1, 2, 3, 4, and so on.
3. Negative numbers: Whole numbers also include the negative counterparts of the positive counting numbers. For example, -1, -2, -3, -4, and so on. Negative numbers are represented by placing a minus or negative sign (-) before the number.
4. Natural numbers: Although whole numbers include zero, natural numbers do not. Natural numbers start from 1 and continue indefinitely. So, natural numbers are a subset of whole numbers. In other words, all natural numbers are whole numbers, but not all whole numbers are natural numbers.
Whole numbers can be used in various mathematical operations, including addition, subtraction, multiplication, and division. They are mainly used for counting, ordering, and representing quantities that do not involve fractions or decimals.
It’s important to note that whole numbers are a fundamental concept in mathematics and are taught at an elementary level. They provide a foundation for understanding more complex number systems such as integers, rational numbers, and real numbers.
