About These Bases

Base 26

In base 26, each digit position represents a power of 26: the rightmost digit counts individual ones, the next counts groups of 26, the next counts groups of 26×26, and so on — the same place-value idea as base 10, just with 26 distinct digits instead of ten.

Base 10

Base 10 works the same way: the rightmost digit counts ones, the next counts groups of 10, the next counts groups of 10×10, and so on, using 10 distinct digits.
