About These Bases

Base 40

In base 40, each digit position represents a power of 40: the rightmost digit counts individual ones, the next counts groups of 40, the next counts groups of 40×40, and so on — the same place-value idea as base 10, just with 40 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.
