Algebra and Trigonometry with Analytic Geometry, 13th Edition

I am an adult returning to collage at 59. As you may imagine and higher math training I received has long been forgotten. The fast pace teaching was leaving me without a clue as to what I needed to do in this course. While the text book had answers to the odd questions, with out an explanation of how they were obtained they weren't much use. When I went to school way back then we didn't study algebra, so I wasn't up to speed in the subject as were the younger students just out of high school. This companion to the text book has the odd answers and how they were done, along with explanations. If you are having a hard time you need this book.
