Webwe hear the word symmetry, we normally think of group theory. To reach his conclusions, Galois kind of invented group theory along the way. In studying the symmetries of the solutions to a polynomial, Galois theory establishes a link between these two areas of mathematics.

The intuition behind Galois Theory, is that in order to find solutions based on radicals (polynomial functions of the coefficients), one has to do it in a consistent step-by-step manner.
