About These Bases

Base 11

In base 11, each digit position represents a power of 11: the rightmost digit counts individual ones, the next counts groups of 11, the next counts groups of 11×11, and so on — the same place-value idea as base 10, just with 11 distinct digits instead of ten.

Base 12

Base 12 works the same way: the rightmost digit counts ones, the next counts groups of 12, the next counts groups of 12×12, and so on, using 12 distinct digits.
