In base 20, each digit position represents a power of 20: the rightmost digit counts individual ones, the next counts groups of 20, the next counts groups of 20×20, and so on — the same place-value idea as base 10, just with 20 distinct digits instead of ten.
Base 52 works the same way: the rightmost digit counts ones, the next counts groups of 52, the next counts groups of 52×52, and so on, using 52 distinct digits.
