10/6/2019 -- Olympiads 1: Problems about Digits and Base Representations

We will discuss a few properties concerning representations of nonnegative integers and rationals in a general base (such as divisibility criteria), and particularly in base 10. Then we will apply this knowledge to several Olympiad-type Number Theory problems.

Homework: Problems 8 and 9b, 9c.
