## anonymous 4 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. anonymous

ok... thank you

5. anonymous

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...}

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

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

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

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

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.

@windsylph

21. maheshmeghwal9

23. anonymous

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

24. maheshmeghwal9
