Trust me when I say this the best Alegbra guide on the market. I know because I tried them all(no joke.) As an adult, who never had Algebra in high school, I was not prepared for it in college. And there are few college courses that go all the way back to the beginning, mine expected that you already had basic algebra fundamentals. The guide along with the workbook, actually replaced my textbook. The textbook was simply put, confusing, and unrelatable. The guide, and workbook were lifesavers for me. The clear, precise and easy to understand examples clarified much of what confused me. And associating all of the properties and laws to analogies worked liked a charm. In fact, I soon learned I knew th properties and laws better than my classmates and began using the analogies to explain them so they to could remember all the little tricks this guide taught me. My teenage son, who has struggled with Algebra, now has his own copies and wonders why his teachers have never thought to make it so easy to learn.
