Give a real word example of how we use postive and negative numbers? make sure you can explain the meaing of 0.

We use positive and negative numbers when we deal with money.  How much money you have can be represented by positive or negative numbers.  If you have money, then you have a positive number, if you have no money, then you have zero dollars, but if you owe money, then you have a negative amount of money.

Zero is neither a postive nor negative number, and in this case, zero means you posess no money.
