is zero a number?

Answer 1

Yes. It's an even number, even.

And just remember, zero is different from nothing.

Answer 2

Well, before this starts to sound like a Zen koan, let’s look at how we use the numeral “0.” Arab and Indian scholars were the first to use zero to develop the place-value number system that we use today. When we write a number, we use only the ten numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. These numerals can stand for ones, tens, hundreds, or whatever depending on their position in the number. In order for this to work, we have to have a way to mark an empty place in a number, or the place values won’t come out right. This is what the numeral “0” does. Think of it as an empty container, signifying that that place is empty. For example, the number 302 has 3 hundreds, no tens, and 2 ones.
So is zero a number? Well, that is a matter of definition, but in mathematics we tend to call it a duck if it acts like a duck, or at least if it’s behavior is mostly duck-like. The number zero obeys most of the same rules of arithmetic that ordinary numbers do, so we call it a number. It is a rather special number, though, because it doesn’t quite obey all the same laws as other numbers—you can’t divide by zero, for example.

Answer 3

Absolutely. It is an even number, leaving no remainder when divided by 2. It is also the additive identity, meaning that adding this number to any number (even 0) leaves that number unchanged.

People in the middle ages were fearful of the number zero because it has no multiplicative inverse, and is in fact the only real number with this property. Our modern calendar even now reflects this fear: note that ther is no day 0 on the calendar. In fact, calendar calculators can be improved by designating the last day of the previous month as the "zeroeth day" of the current month. December 31 can be considered as the "zeroeth day" of the year. I prefer designating Sunday as the "zeroeth day" of the week, then
Monday=1, Tuesday=2, Wednesday=3, Thursday=4, Friday=5, and Saturday=6.

We should consider all starting points as beginning with 0, as an abbreviation for "the origin". For example, when adding lengths, prononce your starting point as "0", then advance in the direction you want to go once pronouncing "1", and advance again, pronouncing "2", and so forth.

Answer 4

Yes, and its one of the most important numbers of all. How many Nobel Prizes do I have? Zero. How many Olympic gold medals do I have? Zero. How many times have I danced on Mars? Zero. The number zero is EXTREMELY important, and its invention was a breakthrough in mathematics, because it allowed for the concept of "none at all" to be represented by a symbol, and to function as a "place holder" in written numbers (1,030,101).

Answer 5

Yes its an even number because it makes a pair

0 2 4 6 8 10

you always start at 0 when you count you never go

1 2 4 6 8 10

YES 0 is a number

Answer 6

yes, zero is a number infact it is the first number of the whole number system and counting numbers. the number zero divides the negetive number from the positve number on the number line.

Answer 7

Yes, my friend.

In the past people did not have zero in their counting system so whenever they wanted to write numbers like 1002 they left spaces to indicate the zeros. Pretty stupid, huh?

Just imagine if they wanted to write 1,000,004

Answer 8

Yes if someone asks you something you never did how many times did you do it 0

Answer 9

zero is definetly a number..It comes before one...just nobody uses it..

Answer 10

Yes.
