In base 43, each digit position represents a power of 43: the rightmost digit counts individual ones, the next counts groups of 43, the next counts groups of 43×43, and so on — the same place-value idea as base 10, just with 43 distinct digits instead of ten.
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.
