About These Bases

Base 8

In base 8, each digit position represents a power of 8: the rightmost digit counts individual ones, the next counts groups of 8, the next counts groups of 8×8, and so on — the same place-value idea as base 10, just with 8 distinct digits instead of ten.

Base 4

Base 4 works the same way: the rightmost digit counts ones, the next counts groups of 4, the next counts groups of 4×4, and so on, using 4 distinct digits.
