### Calculator Digits

For most calculations we use only ten different digits (0 to 9). The number zero, becomes a placeholder for a new set of numbers. The next set consists of 10 times the amount, and then the next 10 times again. Just like when we tried to fold the paper, each set of numbers grows exponentially. By using zero as a place holder, we can write incredible large numbers in a very small amount of space.

Look at the following and see how each successive row contains more possible number combinations than the first.

- 1 = ONE
- 10 = TEN
- 100 = ONE HUNDRED
- 1,000 = ONE THOUSAND
- 10,000 = TEN THOUSAND
- 100,000 = ONE HUNDERED THOUSAND
