The base five system uses
groups of five just like our base ten system uses groups of ten. The
possible digits in the base five system are 0, 1, 2, 3, and 4, so the
Counting in base five can be modeled by counting with only one hand instead of both hands, like we do in base ten. We can also use the idea of money, with pennies, nickels and quarters. This number system can also be modeled using base five blocks. |
