base ten number system

Definition

Our number system, called "base ten," uses only the digits 0 through 9, and the position of each digit tells you its value (like how the '2' in 20 is different from the '2' in 200). It's based on groups of ten, so ten ones make a ten, ten tens make a hundred, and so on.

base ten number system is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
