Answer 8

If we want to write any number, we have ten digits we can use: 0 1 2 3 4 5 6 7 8 9. If you notice, there is no one digit for the number ten- we need to use two digits, the 1 and the 0. We can only count to nine without the need for two digits. Therefore, we use base ten in order to make bigger numbers.
