"This book's strength is that it is exactly what it purports to be-a casual stroll through sometimes complicated mathematical relationships without the heavy lifting of having to understand unfamiliar mathematical notations or ideas. . . . This book is a nice little treasure that a teacher could use to introduce a lesson on currency, recursion, or many other varied mathematical topics. The best thing it does is invoke feelings of wonderment."
