Query: How to be frustrated with algebra without really trying.

I am in the midst of taking the third in a succession of algebra courses using this particular series of textbooks. This book, by far, surpasses the others in difficulty of use! Many of the illustrations seem to have little or no bearing upon the problems given and the explanations can be obscure at best. The book is also poorly edited making matters even worse. If you have never before experienced the height of frustration, I would recommend this book as a means of getting there. The sad part is that I really wanted to like algebra and this book has made it almost impossible.
