Integers

Is zero an integer?

[bibblebub]

yes

[Prudie]

yes

[factor-fiction]

One definition is: a member of the set of positive whole numbers {1, 2, 3, . . . }, negative whole numbers {-1, -2, -3, . . . }, and zero {0}.

We just need Buenchico now to confirm it too

[pixie373]

Yes

>>>We just need Buenchico now to confirm it too

Hmmm, let me think . . . . .

Er, . . .

Hang on a moment, . . .

Erm, . . .

Oh, YES!
;-)

[ToraToraTora]

so ForF, whole numbers, then!

yes zero is and integer but what is worrying me is why is there doubt enough to even ask the question?

[maggiebee]

Because we're not all as brainy as you TTT.

[ToraToraTora]

no maths or brains needed, look it up in the dictionary!

Integer = Whole number! tada!

[maggiebee]

Oh how I wish I was as clever as you - NOT.

[ToraToraTora]

you mean you are happy to be less intellegent? that's very interesting because I was just going to ask a question related to that sort of attitude.

Good question dondon

TTT the question is asked for us who wonder why there is a letter for integers without zero N (bold N that one)
and a different one Z for the set that includes zero

and also in this: http://en.wikipedia.org/wiki/Natural_numbers

you have this:
There is no universal agreement about whether to include zero in the set of natural numbers: some define the natural numbers to be the positive integers {1, 2, 3, ...},

so go on asking Donjon and (some of us) will be pleased to help

Good point , PP.

On a similar topic I knew an experienced maths teacher who swore blind that 0 was not an even number. She could talk for ages about it but I never understood her arguments.
