## Ray951 3 years ago is 0 a natural number?

1. ParthKohli

Nope

2. ParthKohli

Natural numbers are positive numbers that start from 1.

3. ParthKohli

0 is every number but a natural number.

4. Ray951

ok... thank you

5. windsylph

About half of math literature consider it as a natural number, and about half consider it as not..

6. ParthKohli

Well actually natural numbers are {1,2,3...}

7. Calcmathlete

THink of it this way. natural numbers are numbers you'd use in counting.

8. windsylph

My textbook in discrete mathematics, for example, includes 0 as a natural number.Although personally, I don't haha.

9. waterineyes

Natural Numbers are the counting numbers, the number we use when we are counting.. Whole Numbers are the Natural Numbers including 0 in it...

12. bernardthe1st

why natural numbers considered natural?

13. Ray951

dunno

14. maheshmeghwal9

becoz they r natural lol

15. windsylph

Yep that link says it all. Some include 0 as a natural number.

16. Wired

Natural @bernardthe1st Read the top of the link I posted. Natural as in what you count with.

17. windsylph

Excluding or including 0 as a natural number has their own merits, mathematicians say.. So there's really no standard answer to this. It just depends on the context of where you're using natural numbers. And yes please read @Wired's post above, he has a link explaining it.

So as a summary; The whole world doesn't take 0 as a natural number though there are some exceptions. & Even if u give exam u should write 0 = natural no. otherwise u know what is the result LOL. @Ray951 k! my friend

19. maheshmeghwal9

@w is right.

20. maheshmeghwal9

@windsylph

21. maheshmeghwal9

sorry in that para $0 \ne \natural$

22. maheshmeghwal9

natural

23. cornitodisc

0 is a natural number because it is a real number.

24. maheshmeghwal9

write it in exam & wt would u get; u know @cornitodisc The question contains philosophy. u should remember only @Ray951 $0\color{red}{\ne} \text{{N} No.}$
