This book
explains the following topics: Groups, The Sylow theorems, The Jordan-Holder
theorem and solvable groups, Free groups and free products, Modules,
Localization of rings and modules, Free modules and rank, Infinite Galois
theory, Cyclotomic fields, Kummer Theory , Cyclic Galois extensions,

This book is intended as a sequel to
our Elementary Algebra for Schools. The first few chapters are devoted to a
fuller discussion of Ratio, Proportion, Variation, and the Progressions, and
then introduced theorems with examples.
