This first edition of "Mastering An Axiomatic Approach" has been retired; however, the second edition is available for sale at Amazon.com and other book sellers. The second edition, which is clearly labeled on the front cover as such, contains almost 40% more material, covering more advanced topics in algebra like factoring, graphing, functions, logarithms, and imaginary numbers; please do a search for, and take a look at the second edition; I promise you will gain a perspective of algebra, and mathematics in general, that few others have.
