About These Bases

Base 5

In base 5, each digit position represents a power of 5: the rightmost digit counts individual ones, the next counts groups of 5, the next counts groups of 5×5, and so on — the same place-value idea as base 10, just with 5 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.
