is zero a number?

Question

why is zero a number?

Answer 1

yes

Answer 2

Zero is a number; in fact, it is a real number. It is on the number line right between 1 and -1. You can add, subtract, and multiply with 0 and get real answers. You can divide numbers into zero and get a real answer, zero. You can't say anything like that about either nothing or infinity. It is not on the number line and you can't do computations with it. Now, consider 1/0. You know that 1/1 =1, 1/0.1 = 10, 1/0.01 = 100, 1/0.001 = 1000, etc... Pick a power of 10 as large as you want and I can find a number larger than 0 that I can divide into 1 and get your number as a result. In other words, as we divide numbers into 1 and those numbers get closer and closer to 0, the quotient gets larger and larger with no boundary. We conclude then, that 1/0 = infinity. hope this helps - i had a math teacher who was a BIG FAN of the number 0. this brought back some not so fond memories. lol

If you don't think it a number try count $100 dollar bills....you would just have $1.

Yes. But then what do you mean by 'number'? There's a lot of different kinds of numbers: natural numbers, whole numbers, rational numbers etc. Zero isn't a natural number. Natural numbers are defined as 'the number of elements in certain sets' so to speak without getting too technical. All the other kinds of numbers come from our algebraic needs: the whole
numbers arise from the need to be able to subtract any two numbers, the rationals from the need to divide numbers. The reals were invented because some calculations couldn't be performed with rational numbers alone.

The word zero comes through the Arabic literal translation of the Sanskrit śūnya, meaning void or empty, into ṣifr (صفر) meaning empty or vacant. Through transliteration this became zephyr or zephyrus in Latin. The word zephyrus already meant "west wind" in Latin; the proper noun Zephyrus was the Roman god of the west wind (after the Greek god Zephyros). With its new use for the concept of zero, zephyr came to mean a light breeze—"an almost nothing."[1] The word zephyr survives with this meaning in English today. The Italian mathematician Fibonacci (c.1170-1250), who grew up in Arab North Africa and is credited with introducing the Hindu decimal system to Europe, used the term zephyrum. This became zefiro in Italian, which was contracted to zero in the Venetian dialect, giving the modern English word.

Answer 4

zero is like nay other number ... when you count you may not start from zero you probably start from 1 however0 is just like all numbers in other subjects may mean nothing and that is it but in math it is like any other number and can be used in most operations

Answer 5

because every number have to start with zero

Answer 6

0 divided by 0 = 1

It's a number, it's at the top with the numbers on my keyboard

Answer 7

Of course it is its a real number.. honest

Answer 8

yes

Answer 9

yes it is.

It's the number representing none.

Answer 10

its like the middle, neither negative or postive.
