Problemas de ingenio para principiantes

Open this book and you'll discover that's not true. Inside, you'll find a wide variety of challenges that will make you think creatively until you solve them, while simultaneously strengthening your logical and mathematical thinking. Don't worry if you feel that math isn't your thing. This book has been designed so that anyone with a primary school education can get the most out of it. Whether you're young or old, you'll enjoy testing yourself again and again. But before you begin, promise yourself not to look at the solutions until you're absolutely sure you don't know how to solve the challenge. If you accept this invitation, you'll face geometric puzzles, problems with sticks and coins, solitaire, hidden drawings, continuous-line figures, optical illusions, number sequences, scales and weights, clock riddles, paradoxes, and problems that explore everything from perfect, deficient, and abundant numbers to the most surprising lateral thinking. Go for it! Thinking can be fun, too.
