Download or read book Hashi written by Alastair Chisholm and published by Crombie Jardine. This book was released on 2006-05-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hashi (short for Hashiwokakero, meaning "build bridges") is a new logic puzzle from Japan. In Hashi, the goal is to join islands together with up to two vertical or horizontal bridges, so that every island is connected. The larger in number value the island, the more bridges connect to it (an island of size 6 must be connected to 6 bridges), and no bridge can cross another. Successful logic puzzles have certain things in common: a unique game with one solution, easy to pick up, fun and challenging, able to be put down and picked back up again. Hashi has all these qualities, and puzzle master Alastair Chisholm has created 201 puzzles in three levels of difficulty--Easy, Medium, and Hard; you'll be thinking about them even when you're not working on them.

Download or read book Killer Kakuro written by Mark Huckvale and published by Phoenix. This book was released on 2005-12-07 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hooked on su doku? Then move on up to kakuro! Kakuro is the latest Japanese puzzle craze for all those who thought they had reached the limit in logic puzzles. Kakuro is all about numbers, and like su doku it is solved by using logic, with absolutely no guesswork. However, Kakuro takes puzzling a step further: it requires simple arithmetic skills as well as reasoning. But don't worry if maths isn't your strong point. While some of the logic relies on you being able to add up, the sums only ever involve a few single digits, and the totals in this book are never more than 45. You don't need to be a maths whiz, nor do you need to have a calculator handy. You will have no difficulty in doing the sums in your head. As with the incredibly addictive su doku, the fun in doing kakuro is working out the logic that gets you from the starting position to the single solved grid of digits. So if you're bored with su doku - kakuro is the next logical step . . .

Download or read book Alex s Adventures in Numberland written by Alex Bellos and published by A&C Black. This book was released on 2010-04-05 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tenth anniversary edition of the iconic book about the wonderful world of maths Sunday Times bestseller | Shortlisted for the BBC Samuel Johnson Prize 'Original and highly entertaining' Sunday Times 'A page turner about humanity's strange, never easy and, above all, never dull relationship with numbers' New Scientist 'Will leave you hooked on numbers' Daily Telegraph In this richly entertaining and accessible book, Alex Bellos explodes the myth that maths is best left to the geeks, and demonstrates the remarkable ways it's linked to our everyday lives. Alex explains the surprising geometry of the 50p piece, and the strategy of how best to gamble it in a casino. He shines a light on the mathematical patterns in nature, and on the peculiar predictability of random behaviour. He eats a potato crisp whose revolutionary shape was unpalatable to the ancient Greeks, and he shows the deep connections between maths, religion and philosophy. From the world's fastest mental calculators in Germany to numerologists in the US desert, from a startlingly numerate chimpanzee in Japan to venerable Hindu sages in India, these dispatches from 'Numberland' are an unlikely but exhilarating cocktail of history, reportage and mathematical proofs. The world of maths is a much friendlier and more colourful place than you might have imagined. This anniversary edition is fully revised and updated.

Available in PDF, EPUB and Kindle. Book excerpt: How to write mathematical proofs, shown in fully-worked out examples. This is a companion volume Joel Hamkins's Proof and the Art of Mathematics, providing fully worked-out solutions to all of the odd-numbered exercises as well as a few of the even-numbered exercises. In many cases, the solutions go beyond the exercise question itself to the natural extensions of the ideas, helping readers learn how to approach a mathematical investigation. As Hamkins asks, "Once you have solved a problem, why not push the ideas harder to see what further you can prove with them?" These solutions offer readers examples of how to write a mathematical proofs. The mathematical development of this text follows the main book, with the same chapter topics in the same order, and all theorem and exercise numbers in this text refer to the corresponding statements of the main text.

Download or read book Mensa Kakuro written by Conceptis Puzzles and published by Sterling Publishing Company, Inc.. This book was released on 2006-08 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: What could be more appealing to Mensa members--or anyone who enjoys a good challenge--than a cunning test of intelligence and logic? That's exactly what these 250 puzzles provide. The trick to kakuro is in making it all add up: the game begins with a grid that looks like a crossword, except that some squares contain small numbers in the corner. Fill in all the empty boxes using the numbers 1 to 9 without repeats so that the sum of each horizontal set of digits equals the number in the black triangle to its left, and the sum of each vertical set of digits equals the number in the triangle above it. The kakuro puzzles start out simple...and get more difficult as the book progresses.

Download or read book Combinatorics A Very Short Introduction written by Robin Wilson and published by Oxford University Press. This book was released on 2016-04-28 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: How many possible sudoku puzzles are there? In the lottery, what is the chance that two winning balls have consecutive numbers? Who invented Pascal's triangle? (it was not Pascal) Combinatorics, the branch of mathematics concerned with selecting, arranging, and listing or counting collections of objects, works to answer all these questions. Dating back some 3000 years, and initially consisting mainly of the study of permutations and combinations, its scope has broadened to include topics such as graph theory, partitions of numbers, block designs, design of codes, and latin squares. In this Very Short Introduction Robin Wilson gives an overview of the field and its applications in mathematics and computer theory, considering problems from the shortest routes covering certain stops to the minimum number of colours needed to colour a map with different colours for neighbouring countries. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
