Why do we study integers?

We study integers because they form the foundation of number theory and are essential for understanding basic mathematical concepts. Integers are used in various real-world applications, including computer science, cryptography, and finance. Additionally, they help develop critical thinking and problem-solving skills, as they are involved in operations such as addition, subtraction, multiplication, and division. Understanding integers also lays the groundwork for more advanced mathematical topics, such as algebra and calculus.
