About These Bases

Base 12

In base 12, each digit position represents a power of 12: the rightmost digit counts individual ones, the next counts groups of 12, the next counts groups of 12×12, and so on — the same place-value idea as base 10, just with 12 distinct digits instead of ten.

Base 9

Base 9 works the same way: the rightmost digit counts ones, the next counts groups of 9, the next counts groups of 9×9, and so on, using 9 distinct digits.
