What are Natural Numbers? Definition, Examples,Facts and what are the count numbers

The natural numbers are the basis for many other number

 combinations, such as the prime numbers And natural numbers we

 see every day as we use them to drive  calculations, measure

 temperatures, and many other uses In this article we will learn about

 what the natural numbers are, what is their definition, do they have

 significance in our life, the most important observations for natural

 numbers, is zero a natural number or not, is the number 2.5 a natural

 number or not. We will learn all of that and more on the mathematics page in English





? What is the natural number

Natural numbers are part of the number system that includes

 all positive integers and natural numbers It is a part of real

 numbers that does not include only positive integers except

 for decimal  fractions, negative numbers and the number Natural is any positive integer, such as 1, 2, 3, 4, and

 5, except for the infinite, and some  scholars have added the

 number zero or in another form. About it that it contains a

 group of counting numbers, and some scholars added zero






? What are the count numbers

They are the positive numbers that start with the number one

 and end with the infinite and are

 drawn to the right of the number line from 1 to infinite

Examples of numbers counting 1, 2, 3, 4, 5, 6, and 7 to infinity

Intersection, union and difference between groups

  • Natural numbers The union of numbers by count equals natural numbers
  • Natural numbers The difference in count numbers equals group zero
  • The number of count difference of natural numbers equals phi
  • Count setting Difference count count equals phi
  • Natural numbers The difference of natural numbers is equal to phi
  • Zero natural number difference equals phi
  • Zero difference count numbers remain zero
Examples of application

?   What are the natural numbers less than 10

Solve the problem with numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9

?  What are the individual natural numbers less than 8

Solve the problem with numbers 1, 3, 5, and 7

?  What are the marital natural numbers less than 13

Solve the problem The numbers are 2, 4, 6, 8, 10, and 12

? What are the count numbers less than 6

Solve the problem The numbers are 1, 2, 3, 4, and 5

?  What are the natural numbers confined between 14 and 20

Solve the next problem: The numbers are 15, 16, 17, 18, and 19

?  What are the marital natural numbers confined between 100 and 110

Solve the next problem: The numbers are 102, 104, 106, and 108

?  What are the individual normal numbers between 50 and 60

Solve the next problem: The numbers are 51, 53, 55, 57, and 59

 ? Is the number 0 a natural number

A natural number is any positive number, and some scholars have added zero

? Is 2.5 a natural number

The number 2.5 is not a natural number because natural numbers do not have decimal numbers


Operations on natural numbers in addition and multiplication

Addition and multiplication there are great similarities between them

Commutative property

Addition is a commutative process where 4 + 5 = 9 and 5 + 4 = 9 We conclude that addition is

 a commutative process and that any natural number + natural number = natural number

Multiplication is an exchange process where 3 x 5 = 15 and 5 x 3 = 15 We conclude that

 multiplication is a commutative operation i.e. a natural number x a natural number = a natural

 number

Locking property

Addition is a closed process where (4 + 5) + 2 = 11 and (2 + 5) + 4 = 11 We conclude that

 addition is a commutative process.

Multiplication is a closed process where (2 x 3) x 4 = 24 and (3 x 4) x 2 = 24 We conclude that

 multiplication is a commutative operation

Collective neutral

The additive neutral in mathematics is 0

The multiplicative neutral

The multiplicative neutral in mathematics is 1

Merge property

Inclusion is possible in addition and multiplication since addition and multiplication are both

 commutative operations

Operations on natural numbers in subtraction and division

The subtraction and the division there are great similarities between them

The commutative property

Subtraction is not a commutative process like 5 - 2 = 3 and 2 - 5 = -3 We conclude that

 subtraction is not a commutative process and any natural number - natural number = natural

 number

Division is not an exchange process where 15/3 = 5 and 3/15 = 1/5 we conclude that division

 is not a commutative process and any natural number / natural number = natural number

Locking property

Subtraction is not a closed process since (4 - 2) - 1 = 1 and (1-2) - 4 = -5. We conclude that

 subtraction is not a closed process.

The division is not a closed process as (4/2) / 3 = 2/3 and (3/2) / 4 = 3/8 We conclude that the

 division is not a closed operation

Forgiveness property

Merging is a property that is not possible in division and subtraction because subtraction and

 division are not a commutative process

Important notes

  1. The smallest natural number is one
  2. The smallest whole number is zero
  3. Every integer is a natural number except zero
  4. All natural numbers are whole numbers, but all integers are not natural numbers
  5. Negative numbers, fractions, and decimals are neither natural nor whole numbers
  6. The natural numbers are divided into even and odd numbers
