About These Bases

Base 20

In base 20, each digit position represents a power of 20: the rightmost digit counts individual ones, the next counts groups of 20, the next counts groups of 20×20, and so on — the same place-value idea as base 10, just with 20 distinct digits instead of ten.

Base 30

Base 30 works the same way: the rightmost digit counts ones, the next counts groups of 30, the next counts groups of 30×30, and so on, using 30 distinct digits.
