What is our number system based on?
We name number systems based on the number of digits that are used in the system. Our standard number system is called base-ten because there are ten base figures. Those are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Any number larger than 9 and we have to move to a different slot. In the past, you've probably learned about different slots for numerals.
