Zero is a number that means nothing or empty. According to mathematics, zero (0) is a number with the value null. It's a number that's neither positive nor negative. Think of it like this:
- If you have zero cookies, you don't have any cookies at all.
- If the temperature is zero degrees, it's very cold!
- If you score zero points in a game, you didn't get any points.
Zero is a really important number because we use it all the time!
