Algebraic Structures

Definition

Algebraic structures are mathematical constructs that consist of a set equipped with one or more operations that satisfy specific axioms. They form the foundation of various branches of mathematics by providing a way to study the relationships and properties of numbers, shapes, and functions in a structured manner. These structures help in understanding the general behavior of mathematical systems, linking to key ideas in logic and computer science.
