Is zero a number?

Of course.

It could be a number or not depending on context. It could be the absence of anything (thus, if it isn't anything, then by definition it can't be a number). If it's used in a mathematical operation, obviously it has to represent a number. I can't add 3 and 0 if zero isn't a number, just like I can't add 3 and oranges.

Yes, not that it really matters today.

Yeah, its a whole number

We use zero in daily life as a number (pick a number from zero to ten, for example), but some people consider it not a number, but an absence of number. Confusing enough? I would give you a better definition, but dictionary.com is down (as are a lot of sites-this is probably related to the terrorist attacks in NYC & D.C.).

A number is a representation of how many of something is at state. I means there is a single object. Two means two objects. Zero means there are no objects, therefore zero is a number, as it represents how many of something is at state.

Yes, what else would it be?

No, it's a concept.

Yes. It is also a place keeper. Zero is essential in mathematics.

Yes, it's part of the binary code (which is composed of the numbers 1 and 0) so that makes it a number! Does that make sense?

I understand, BrianW, everything does seem trivial today...

Not according to the Romans.

yes, i guess. i am not in the mood to answer any of these today. i am soooo sad!

Uh...yes and no. Zero is a number in the sense that grey is a colour.

What else could it be?

I think so

Yep. It's a crucial part of numbers. Without zero, $1,000,000,000,000,etc. would simply be $1.
I rest my case.

Yes today IS a very sad day.
Hope you feel better in the next few days.

Yes, but it doesn't belong to every group of numbers.

From the dictionary definition of "number" I would say yes.

well, i felt even worse this morning. i was crying after watching some of the news. now i feel just blah! so sad, such a loss and so senseless to do.
and then i think of how sad it will be if we kill innocents as well. i know we have to do something but at times it is such a vicious cycle. anyway, thanks, i will feel better in a bit i guess!

I was crying this morning too

I know babe I feel the same. I just don't know what this world is coming to.Tell you what,why don't you let me to sculpt your name in styrofoam in your favorite color,to cheer up up???

I have just taken Maarten & Jens styrofoam names to the post office this afternoon.I don't know how long it's going to take them,to get it now,with all these security measures going on.All you have to do is e-mail me your snails address & your favorite color & I'll sculpt your name & send it to you.
The most popular colors requested here at SC are red,blue,lavandar,purple,teal,black,green,pink,yellow,grey & burgundy.The only colors not yet requested are silver & gold. Here's my E address.... dabprovin@msn.com
don't forget to include your color.I'll send yours at the same time that I mail Edhduannua.

Cheer up!!! Thing will calm down & work out soon.

I like silver...

Okay then,send me your snails mail address & I'll send you your name also Oscar.Do you want it in your SC user name or your birth name??

birth name.
It will be coming from Oscar_d@bigfoot.com

styrofoam names in my favorite color?? that is cool!! i will send the email.

go study math, of course it's a number.

Jettles my dear,you forgot to include your favorite color,when you e-mailed me tis morning.

You didn't tell me what color,but most important,you didn't include your snails mail address.

I know. I wasn't sure yet if I wanted to send it to you.
Silver.

No problem,I'm in the middle of doing Enheduanna & Jettles names right now anyways.Their names should keep me pretty busy for the next week at least.

zero is a number, isn't it?

Yes, it is an integer just like 3 or 4.

Yes, it is a place holder, and also a way of comparing having some and having none, although that's probably a terrible way of explaining it. Good thing I'm not a math teacher!

it is nothing, nada, zilch, zippo.......

zero is the absence of a number a place keeper yes a number no. 3+0=3 3-0=3 see it changes nothing.

yes it has to be.each big number is a bunch of small numbers. If 0 is in the big number it has to be a number on its own

It's an absence of number (I think) I absolutely stink at math. I got onto a site called 'Confusion'. you have to really think about your answers sometimes and I just love it. I need the exercise!My kids are on it too. We bounce off each other all the time for hints.My son is very smart so, he usually gets the answers first.
