“zero”的概念、定义、习题解题方法及翻译-数学辞典

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.

• When we add zero to a number the result is just the number, unchanged.
• When we multiply a number by zero we get zero.

Zero is also used 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.
