Playing with mathematical riddles can be an intriguing and fun-filled pastime — 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.

Collected over several years by Peter Winkler, of Bell Labs, dozens of elegant, intriguing challenges are presented in Mathematical Puzzles. The answers are easy to explain, but without this book, devilishly hard to find. Creative reasoning is the key to these puzzles. No involved computation or higher mathematics is necessary, but your ability to construct a mathematical proof will be severly tested--even if you are a professional mathematician. For the truly adventurous, there is even a chapter on unsolved puzzles.

OPCULATO è il nome di un divertente gioco rompicapo con operatori aritmetici che aiuta a migliorare le capacità aritmetiche, memoria, logica e deduzione. I rompicapo sono stati creati apposta per entrare in queste abilità utilizzate nella vita quotidiana. I rompicapo Opculato richiede le capacità aritmetiche per scegliere quale operatore aritmetico (+,-,/ oppure *) va inserito nella casella vuota per ottenere l'equazione determinata. Questo divertente gioco sviluppa la logica mentale e le capacità di deduzione che richiedono di memorizzare quale operatore aritmetico (+,-,/ oppure *) risolverà l'equazione. Per risolvere le equazioni più lunghe dovrete provare diverse combinazioni di operatori aritmetici e memorizzare dove sono stati inseriti gli operatori aritmetici corretti prima di arrivare all'equazione in basso. All'inizio potete utilizzare la calcolatrice, ma il gioco è molto più divertente e porta grandi vantaggi e soddisfazione se viene eseguito senza di essa. Il modo migliore per perfezionare tutte capacità è praticarle; Opculato offre la possibilità di ottimizarle tutte. OPCULATO non è un gioco interattivo e quindi vi costringe a risolvere mentalmente le operazioni aritmetiche.
