About These Bases

Base 2

In base 2, each digit position represents a power of 2: the rightmost digit counts individual ones, the next counts groups of 2, the next counts groups of 2×2, and so on — the same place-value idea as base 10, just with 2 distinct digits instead of ten.

Base 31

Base 31 works the same way: the rightmost digit counts ones, the next counts groups of 31, the next counts groups of 31×31, and so on, using 31 distinct digits.
