What is natural number and from where it starts from.

            NATURAL NUMBER

Q. What is Natural Number?

= It is your fingers counting numbers.

          OR,

In simplest words, Natural numbers are counting numbers started from 1 and followed by 2,3,4,5,6,7---------------------- so on. 

It is also finger numbers.

Q. From where does the Natural number start?

= It starts from 1  and continues to positive infinity with a difference of 1.

Q3. Is 0 a natural number?

= No 0 is not a natural number. Counting numbers start from 1 hence, it will not natural number.

Q4. Which symbol is used for representing all sets of natural numbers?

= Set of natural numbers are represented by CAPITAL "N".

N= { 1,2,3,4,5,6,7,8,9,10,11,12,13,-------------------------------}

Q5. How many natural numbers are possible in that number system?

= There are infinitely natural numbers that are possible in the number system starting from 1 to positive infinite with a gap of exact 1.

Q6. Write the first ten all-natural number lists.

= First ten counting numbers are { 1,2,3,4,5,6,7,8,9,10}.

Q7. Are all natural numbers are whole numbers?

= Yes, whole numbers are set of all numbers starting from zero followed by all natural numbers.

Whole numbers- 0,1,2,3,4,5,6,7,8,9-------------------------------

Natural numbers= 1,2,3,4,5,6,7,8,9------------------------------

See, in the above representation it is clear that all-natural, numbers are present in the list of whole numbers but all whole numbers (0) are not present in the list of natural numbers.

Q8. Are all whole numbers are natural numbers?

= No, due to 0 it could not possible that all whole numbers are natural numbers. You can better understand with the above representation. 

Q9. Are all natural numbers are rational numbers?

= Yes, we can write all natural numbers in the form of the ratio of numerator and denominator so every natural number will be a rational number.

Example- 1 as a rational number= 1/1 

                 0 as a rational number = 0/1

                15 as a rational number = 15/1

                16 as a rational number = 16/1

Q10. Are all rational numbers are natural numbers?

= No, Because rational number includes the negative number and fraction number but natural numbers are only positive counting numbers. Hence all rational numbers are not natural numbers.

Till now, we have known all facts of natural numbers and their doubts before moving further I want to
