These add a second operation (multiplication) to the group structure. Examples include integers or polynomials. They help us understand how different types of "numbers" behave when you both add and multiply them.

It allows mathematicians to prove that certain things—like trisecting an angle with only a compass and straightedge—are physically impossible based on their algebraic structure.
