Mathematical Curiosities: A Treasure Trove of Unexpected Entertainments by Alfred S. Posamentier (PDF)

Description

An innovative and appealing way for the layperson to develop math skills—while actually enjoying itMost people agree that math is important, but few would say it’s fun. This book will show you that the subject you learned to hate in high school can be as entertaining as a witty remark, as engrossing as the mystery novel you can’t put down—in short, fun! As veteran math educators Posamentier and Lehmann demonstrate, when you realize that doing math can be enjoyable, you open a door into a world of unexpected insights while learning an important skill.The authors illustrate the point with many easily understandable examples. One of these is what mathematicians call the “Ruth-Aaron pair” (714 and 715), named after the respective career home runs of Babe Ruth and Hank Aaron. These two consecutive integers contain a host of interesting features, one of which is that their prime factors when added together have the same sum. The authors also explore the unusual aspects of such numbers as 11 and 18, which have intriguing properties usually overlooked by standard math curriculums. And to make you a better all-around problem solver, a variety of problems is presented that appear simple but have surprisingly clever solutions.If math has frustrated you over the years, this delightful approach will teach you many things you thought were beyond your reach, while conveying the key message that math can and should be anything but boring.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐Posamentier writes nice math books. If you are a math teacher or run a math club you are always looking for great ‘class starters’. This book will provide you with a wealth of information. This book continues in his tradition of excellent math books for those interested in light reading in math.

⭐Very fine book with, as usual, many interesting problems at various levels. Very worthwhile book.

⭐Good, but not what I had hoped for, which was stories I could share with beginning algebra students.

⭐Just as the sub-title states “A treasure trove of unexpected entertainments!” Not just “Math People” will enjoy these stories.

⭐Great book

⭐A lot of the math was over my head, but what I did understand was not that curious. And, by the way, chickens lay one egg a day. so 6 chickens will lay 48 eggs in 8 days, contrary to what the authors claim (32 eggs), as any farm-boy can tell you!!
