This is a wonderful way to learn algebra. The book reads like a fairy tale as a group of people in a distant land learn algebra along with you. The author also has a trigonometry book in the same series and he uses the same characters. I have yet to tackle that book, however.
Algebra Books Every summer I borrow books from libraries near me to see if they would be good for us with the girls for school in the fall. This book is always brought home and I do enjoy Algebra. It is fairly well written and easy to understand.
Great book to learn algebra from. It's taught through a fairytale type of story that seems silly at first but you end up learning without much effort. I used this book in 1989 and years later ordered it for my kids lol
