Elementary number theory is a branch of mathematics that deals with the properties and relationships of integers, particularly through the study of whole numbers and their inherent properties. It focuses on various topics related to numbers, notably primes, divisibility, modular arithmetic, and congruences, without requiring advanced mathematics or tools from other areas.
