Number theory is a branch of mathematics that focuses on the study of properties and relationships of integers.
It explores patterns, distributions, and properties of prime numbers, integers, and fractions.
Classical problems include the Goldbach conjecture, the Riemann hypothesis, and the Collatz conjecture. Number theory has applications in cryptography, coding, and other disciplines.
Additionally, tit contributes to the fundamental understanding of the structure and behavior of numbers in various mathematical and scientific areas.
