About These Bases

Base 25

In base 25, each digit position represents a power of 25: the rightmost digit counts individual ones, the next counts groups of 25, the next counts groups of 25×25, and so on — the same place-value idea as base 10, just with 25 distinct digits instead of ten.

Base 2

Base 2 works the same way: the rightmost digit counts ones, the next counts groups of 2, the next counts groups of 2×2, and so on, using 2 distinct digits.
