A tad harsh, I wasn't referring to 10 and so forth being outside of the naturals, but my textbook says that whilst 0 is real it isn't natural, no need to get angry about it really, I told you I don't know a lot about this and I'm just trying to understand it. I believe my original post said something along the lines of 'forgive me if I'm wrong' and 'I barely understand any of this' so just take it easy.
I'm not picking a fight so need need to tell me I'm acting tough and all that. I'll find the graph I'm thinking of and edit the in if I can find it. I was thanking you by the way, you did clear up some confusion, now all that's left to clear up now is why your angry, I mean, sorry if I got some physics wrong but correct me, don't abuse me.
Edit: I stand corrected, 0 apparently is natural, better re-read that chapter in my book, exams are coming up. "...0 is neither positive nor negative. By some definitions 0 is also a natural number...".
Your explanation still helps though, thanks, I am however more confused than before, ain't that a *****, I'm off to do some much needed maths study!
Any reason why Wikipedia tells me "By some definitions 0 is also a natural number"? I don't see how it could be a conditional sort of thing.
Umm, you guys arguing about 'real' vs 'natural' numbers are wrong...
Those terms just refer to number sets...
Whole: 0,1,2,3... OR All the Natural numbers + 0
Integer: ...-3,-2,-1,0,1,2,3.... OR All the Whole numbers + All the negative numbers
Rational: All the integers + Fractions
Real: All the rational numbers + Numbers that can't be expressed as fractions, e, pi, root 2
Complex: EVERYTHING. All real numbers + imaginary numbers where i (or j) = root -1
Has nothing to do with what numbers are found in nature...
