Zero zero?

  1. Jun 14, 2003 #1
    Is zero anything or something then zero shouldn't be there?
    For a nothing number it still causes us lot of trouble. Any takers?

    I read a theory on the zero which kinda made sense.

    Zero is the number that, when added to any other number, leaves that other number unchanged.

    I'm not really sure what your question is...

    it's also what you have when you have one apple, and then someone takes it away.

    Zero also represents an empty digit in numbers that are more than a single digit
    Can u tell us about it please ?
    Thanks !

    If zero causes us alot of trouble, then it would cause us far more trouble if it wasn't here. Alot of mathematical concepts are dependent on a meaningful figure called zero. Calculus, far example....

    Zero is the additive identity. If it was not there then how could you define the negative numbers (as opposed to being the additive inverse of positive numbers)?

    :wink: Just thought I'd ask. This theory I read was several years ago, but it stuck out as being odd to me. Thanks.
