I've been looking for some free resources to learn a little number theory but I really can't find anything that is at a beginner level, anyone know of any sites or such of where I should start?
Number theory is a branch of mathematics that deals with the properties and relationships of numbers, particularly integers. It involves studying patterns and structures in numbers and their properties.
Number theory is important because it has numerous real-world applications in fields such as cryptography, computer science, and physics. It also helps us better understand the properties and behavior of numbers and serves as a foundation for other areas of mathematics.
Some basic concepts in number theory include prime numbers, divisibility, modular arithmetic, and the fundamental theorem of arithmetic. These concepts are essential for understanding more complex topics in number theory.
A prime number is a number that is only divisible by 1 and itself, while a composite number is a number that has more than two factors. In other words, a prime number can only be divided by 1 and itself, while a composite number has at least one other factor.
Modular arithmetic is a system of arithmetic that deals with remainders. It involves performing arithmetic operations on numbers within a specific range, called a modulus. This concept is often used in cryptography and computer science.
