hmmmm, I'm not sure zeros is really a number. I'm not all that convinced that -2 is even a number.

1) If I was to win £10000000000000000.00 I would hope 0 is a number as I would not like to receive a cheque for £1.
2) It would not be odd for me to win. I would say I have got even.
3) Who cares about numbers who have minus it front of them...I can't buy anything with them...
4)-4 does not have square root. It might have had a root if it had been a plant or a vegetable but numbers don't grow unless you put them in a bank account and get interest. But they still wouldn't get a root...not a aquare one, not a round one! -
