The whole number between −1 and 1, with the symbol 0

Shows that there is no amount.

Example: 6 − 6 = 0 (the difference between six and six is zero)

Zero is not positive and is also not negative.

Zero is also useful as a "place-holder" so that you can write a numeral properly.

Example: 502 (five hundred and two) could be mistaken for 52 (fifty two) without the zero in the tens place.
