Abstract Algebra refers to a broad area of mathematical ideas concerning structure such as groups, rings, fields, lattices, and vector spaces. Number systems like N,Z, or Q have unique properties which allow equations to be stated and solved; new number systems can be constructed by "abstracting" away these properties to get new more complex number systems. These structures unify many disparate areas with a common language and lay the groundwork for such diverse areas as divisibility, gauge theory in physics, quintic equations, and the fundamental group in topology. Many books present groups and fields as proceeding from lists of axioms and then derive theorems. This presents a false impression that this is how the theory developed, when in fact it was the opposite. Mathematicians like Cayley, Galois, and Lagrange studied particular things like permutations or hypercomplex numbers and "abstracted" the properties from these studies.

Prerequisites: Some basic skills in solving equations and "high-school level" math is needed. E.g. Khan Academy's Algebra videos.
