In base 47, each digit position represents a power of 47: the rightmost digit counts individual ones, the next counts groups of 47, the next counts groups of 47×47, and so on — the same place-value idea as base 10, just with 47 distinct digits instead of ten.
Base 28 works the same way: the rightmost digit counts ones, the next counts groups of 28, the next counts groups of 28×28, and so on, using 28 distinct digits.
