Beachy And Blair Abstract Algebra Waveland Press 3rd Edition
Most of the exercises range from easy to moderately difficult and ask for understanding of ideas rather than flashes of insight.. Proofs of theorems do more than just prove the stated results; Saracino examines them so readers gain a better impression of where the proofs come from and why they proceed as they do.. The Second Edition of this classic text maintains the clear exposition, logical organization, and accessible breadth of coverage that have been its hallmarks. HERE
It plunges directly into algebraic structures and incorporates an unusually large number of examples to clarify abstract concepts as they arise. http://liretina.unblog.fr/2021/02/24/hoi4-country-files/
