Val: Are you sure it's the Brown author for AlgebraI: Structure and Function? For that book, I usually read from mathy types that it's the Dolciani author you want. She wrote the books initially I think, then in later years Dolciani and Brown are listed together, and then just Brown. The older versions (Dolciani) are the ones recommended most often, so much so that it's usually just called Dolciani. The older versions are said to be more rigorous. Now, some don't use the Dolciani versions until later b/c they are using it w/ much younger kids and it would be too much for even very advanced kids. NOw this is all just my reading, none of it is first hand. I'd love to hear what you think of the later versions. Mathematically Correct did give only 2 algebra I texts the thumbs up and it was Algebra I:Structure and Function and Foersters and it was a later edition of Algebra I: Structure and Function.
