Playing with mathematical riddles can be an intriguing and fun-filled pastime โ as popular science writer Martin Gardner proves in this entertaining collection. Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem.Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed.Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked."Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 black-and-white illustrations. Review: An amazing book - This is definitely a great book. Somebody says that this book contains many known puzzles and it can't be interesting. If you have never read such books I would recommend you to buy this one. You will enjoy with solving many interesting puzzles. Some of them are extremely fascinated. Review: Nice problem selection. - There are a variety of levels of math puzzles in this book, wide enough to find problems to challenge both middle school and high school students. It is just what I was hoping for.

Mathematical problems for the Beginner
This book introduces mathematical puzzles in very respectable way. Though the puzzles are really mathematical puzzles and the attached solutions explain the essential concepts, you don't need to know lots of knowledge to solve them. However, if you have already read other Martin Gardner's book or mathematical puzzle books, I do not recommend this book. These puzzles are very common and easy kind of ones.

Turned out to be big fun for my dad and my young nephews as well
Got this for my boyfriend and I at his request after he heard about Martin Gardner on a radio show. Turned out to be big fun for my dad and my young nephews as well. 3 generations! I do wish that the answers were separate from the puzzle because it's way too easy to cheat, but of course you can workaround that. Some of the puzzles are huge mind-benders and will leave you scratching your head. Others are more light and fun, but all in all there's something for everyone here.

Thank you for the good book.
I thought it is easy to read and understand puzzles. And more over it is very interesting. Thank you for the good book.

Fun puzzles but strange format
I enjoy math puzzles so was excited to have a variety of puzzles to work on. The puzzles are on various concepts in mathematics and helped me understand concepts and applications in each area. The formatting is strange--it's an older book which is probably part of it. The answers are right next to the puzzles so it's hard not to see the answer before working the puzzle. I would much rather have answers at the end--or at least have a page break between the problems and answers.

A few errors, but OK
Enjoyed right up to page 24. On page 24 he has a puzzle regarding which salary offer would you take. In the puzzle, you are given a choice between two salaries, one starting at $4K and another starting at $2K. But in the solution given, he starts both salaries at $4K. Just a typo I am sure, but not sure which is the error and which is correct.

It never gets old
The "easy-looking" mathematical riddles this book proposed never disappointed. As a maths student, I love counterintuitive questions, it sound crazy, but mathematics can be fun!

Introduction to mathematical logic puzzles for children.
Entertaining Mathematical Puzzles (Math & Logic Puzzles) An excellent little book for my 10 year old grandson. An excellent introduction for children to the world of mathematics which is not just arithmetic but logic as applied to the real world.
