# Natural Numbers: Types, Properties, Solved Examples and More

Natural numbers are part of the number system and include all positive values from 1 to infinity. Natural numbers, often known as counting numbers, They are a subset of real numbers that only include positive integers and exclude zero, fractions, decimals, and negative numbers. On this page, we will look at the definition of natural numbers as well as examples of them.

## What are Natural Numbers?

Natural numbers include all whole numbers, except the value zero. These numerical entities play a significant role in our daily lives. Numerals saturate our surroundings, serving a variety of functions such as tallying items, denoting money values, measuring temperature, indicating time, and so on. The precise subset of integers used for item counting is known as ‘natural numbers’. For example, when quantifying objects, we express quantities such as 5 cups, 6 books, 1 bottle, and so on.

The set of natural numbers is showcased by the letter “N”.

N= {1,2,3,4,5,6,….}

## Natural Number Symbol

In mathematics, a set is an assembly of elements, with numbers being particularly essential in this context. The natural numbers are symbolically expressed as {1, 2, 3, …}, indicating an infinite sequence.

## Is 0 A Natural Number?

No, 0 is not a natural number because natural numbers are defined as counting numbers. When counting items, the enumeration starts at 1 and does not include 0. As a result, 0 is not considered a natural number.

## Types of Natural Numbers

The types of natural numbers are as follows:

### Odd Natural Numbers

Odd natural numbers are integers greater than zero that cannot be divided evenly by 2, leaving a remainder of one when divided by two. The odd natural numbers include 1, 3, 5, 7, 9, 11, and so on.

### Even Natural Numbers

Even natural numbers are whole numbers that divide by two without leaving a remainder. In other words, they are integers bigger than zero that may be represented as 2n, where n is an integer. Even natural numbers include 2, 4, 6, 8, 10 and so on.

## Natural Numbers from 1 to 100

Since natural numbers are counting numbers, the natural numbers from 1 to 100 include:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100.

## Natural Numbers on Number Line

Natural numbers are all positive integers or integers on the right side of 0, whereas whole numbers are all positive integers plus zero.

Here’s how natural numbers and whole numbers are represented on the number line:

## Properties of Natural Numbers

All the natural numbers have these properties:

1. Closure property
2. Commutative property
3. Associative property
4. Distributive property

Let’s see the properties mentioned below:

Note:

1. Subtraction and division may not yield a natural number.
2. Subtraction and division do not follow the Associative Property.

## Solved Examples

1. Find the natural numbers among the following: -1, 0, 3, 1/2, and 5.

Solution,

In mathematics, the set {1, 2, 3, …} represents the natural numbers. Now, since -1 is a negative integer, it is not a natural number. Zero is also not a natural number. 1/2, as a fractional number, is not a natural number. Therefore, among the above integers, the natural numbers are 3 and 5.

1. State true or false with respect to natural numbers.

a.) Zero is a natural number.

b.) All natural numbers are whole numbers.

c.) Every natural number is an integer.

Solution,

a.) False; 0 is not a natural number. It’s a whole number.

b.) True, every natural number is a whole number because it includes all positive counting numbers beginning with 0.

c.) True, all natural numbers are integers since they include all positive and negative numbers, as well as zero.

1. Give first 10 natural numbers.

Solution,

The first 10 natural numbers are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

## FAQs

What are the basic properties of natural numbers?

The four fundamental features of natural numbers in mathematics are described below.
Closure Property
Associative Property
Commutative Property

Is 0 a natural number?

0 is not a natural number. Natural numbers begin with 1 and can be written as 1, 2, 3, 4, 5, and so on. However, 0 belongs to the category of whole numbers and integers.

What are the examples of natural numbers?

Few examples of natural numbers are: 2, 8, 9, 45, 52, 89, 100 and so on.
