Where can I find the answer to the question "Why are there two naughts in the number zero?"?

The answer is that the number zero has a special property. It’s not just any old number, it’s a number that is equal to itself minus itself! This means that if you add one to zero, you get zero. If you subtract one from zero, you also get zero. And if you multiply zero by any other number, you still get zero.
