About These Bases

Base 4

In base 4, each digit position represents a power of 4: the rightmost digit counts individual ones, the next counts groups of 4, the next counts groups of 4×4, and so on — the same place-value idea as base 10, just with 4 distinct digits instead of ten.

Base 18

Base 18 works the same way: the rightmost digit counts ones, the next counts groups of 18, the next counts groups of 18×18, and so on, using 18 distinct digits.
