Abstract Algebra and Solution by RadicalsThis advanced undergraduate level text was recommended for teacher education by The American Mathematical Monthly and praised as a "most readable book." An ideal introduction to groups and Galois theory, it provides students with an appreciation of abstraction and arbitrary postulational systems, ideas that are central to automation.

This advanced undergraduate-level text was recommended for teacher education by The American Mathematical Monthly and praised as a "most readable book." An ideal introduction to groups and Galois theory, it provides students with an appreciation of abstraction and arbitrary postulational systems, ideas that are central to automation.The authors take the algebraic equation and the discovery of the insolubility of the quintic as their theme. Starting with treatments of groups, rings, fields, and polynomials, they advance to Galois theory, radicals and roots of unity, and solution by radicals. Thirteen appendixes supplement this volume, along with numerous examples, illustrations, commentaries, and exercises. Students who have completed a first-year college course in algebra or calculus will find it an accessible and well-written treatment.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
