Elementary Number Theory

Elementary Number Theory is a branch of mathematics focused on the properties and relationships of integers. It explores concepts like divisibility (when one number can be divided by another without a remainder), prime numbers (those greater than 1 that have no divisors other than 1 and themselves), and modular arithmetic (calculating remainders). This field lays the groundwork for more advanced topics and has practical applications in areas such as cryptography, computer science, and coding theory. It emphasizes logical reasoning and proof techniques, helping to unveil the underlying structure of numbers.
