This book offers valuable common sense advice that can be used in a broad array of every day situations. The narrative is very readable and easily accessible to all, only requiring an occasional minimum of mathematical reasoning.For those who are already familiar with the concepts, it is a refreshing summary of the pitfalls of the innumerate. And for those of you who have always considered mathematics to be 'one of your worst subjects', then this book may very well give you a new perpective and teach you something to boot.I found it to be refreshing and entertaining read and recommend it to all.
