Book SynopsisWhen the Guardian relaunched their new Berliner sized paper this autumn, they chose Kakuro as one of their launch vehicles. Kakuro (called Kakro in Japan and Cross Sums in the USA) has become the new number puzzle phenomenon gathering millions of fans worldwide. Older than puzzle favourite Sudoku and played for many years in Japan, Kakuro is best described as a kind of mathematical crossword.Like Sudoku, Kakuro is played on grids of varying sizes. Each grid consists of blank and filled squares similar to a crossword puzzle and the object of Kakuro is to fill in each of the white squares with the numbers 1-9 so that each set of blanks adds up to the total to the left or above. The same number cannot be used more than once in each set. Some filled in squares have a diagonal slash across them with two numbers - one above and one below the diagonal. These are the ''clues'' - the number in the top right corner relates to a horizontal ''clue'' and the one in the bottom left

Oxford University Press, USA Taking Sudoku Seriously
Book SynopsisPacked with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku 2eriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and cTrade ReviewThis well-written book would be of interest to anyone, mathematician or not, who likes solving Sudoku puzzles. * Donald Keedwell, Mathematical Gazette *This is an interesting book. The style is conversational and east to read ... * John Sykes, Mathematics in School *I thoroughly enjoyed this book and do not have any criticisms to make.

Princeton University Press Guesstimation
Book SynopsisEnables anyone with basic math and science skills to estimate virtually anything - quickly - using plausible assumptions and elementary arithmetic. This book presents an array of estimation problems that range from devilishly simple to quite sophisticated and from real-world concerns to silly ones.Trade Review"Dr. Adam and his colleague Lawrence Weinstein, a professor of physics, offer a wide and often amusing assortment of Fermi flexes in a book that just caught my eye, Guesstimation: Solving the World's Problems on the Back of a Cocktail Napkin."--Natalie Angier, New York Times "An important skill of great use ... is the ability to derive an approximate result from insufficient data. Guesstimation is a collection of [problems] gathered from everyday life and various fields. Working out questions ... is both entertaining and enlightening. It may also help foster your career ... because making correct guesses quickly establishes your reputation as an expert."--Stephan Mertens, Science "This book is a stimulating collection that will help the reader to reach informed judgments and will be a useful source of inspiration for mathematics and physics teachers: my only concern is that if my students have read it before they arrive at university, I may have to find a new approach to my first day's teaching."--Tony Mann, Times Higher Education "While few can hope to emulate the brilliance of a Nobel Prize winner like [Enrico] Fermi, coming up with pretty good guesstimates is a skill that can be taught. And that's the aim of Guesstimation. After a quick tutorial, the authors get down to business with a host of wide-ranging worked examples, from estimating the numbers of piano tuners in Los Angeles to figuring out the impact of deforestation on greenhouse gas levels. The results are sometimes surprising."--Robert Matthews, BBC Focus Magazine "[Guesstimation is] a left-brain book that helps you approximate answers to the types of questions actually asked in some job interviews today."--Peter Coy, BusinessWeek "[A] delightful account of mathematical approximation, which instills the beauty and power of the back-of-the-envelope calculation. The puzzles make addictive confidence builders by breaking down tricky questions into manageable parts. Never again will you take a newspaper figure at face value without feeling the need, and confidence, to guesstimate your own figure."--Matthew Killeya, New Scientist "Guesstimation is both enlightening and entertaining. I recommend it to my fellow journalists both as a tool of our trade and as a mind stretcher."--Rony V. Diaz, Manila Times "Any idea what fraction of land in the US is covered by either a roof or pavement? Known as a Fermi problem, this type of question requires the use of reasonable estimation, which is the focus of the book at hand. In the initial chapters, Weinstein and Adam briefly review good 'guesstimation' techniques involving numbers and explain why the use of the geometric mean is preferred over the arithmetic mean."--J. Johnson, Choice "How many people in the world are picking their nose right now? Weinstein and Adam 'guesstimate' the answer to this problem and 79 others, covering chemistry, physics, biology and history. The book is a step-by-step guide to problem-solving using rough-and-ready maths, the kind done on the back of a cocktail napkin. And the authors have kindly left additional questions at the end to get readers started on their own problem-solving expedition."--Cosmos "Physics educators can use this book as a guide to including the important skill of estimation in their courses. Students may find the power of estimation to be a valuable skill and will want to work their way through this book."--Arthur Eisenkrafr, American Journal of Physics "A source of imaginative problems, this book would make a nice addition to a mathematics department library."--Diane Resek, Mathematics Teacher "[I]t's quite obvious that the authors intend their book to be fun, nonthreatening, and user-friendly. There's very little not to like... [T]he book can be for everybody, 'higher-up professionals' who might know math but not physics, as well as students wrestling with 'word problems.' Teachers could very well recommend it to math majors and nonmajors alike, or even use it in the classroom, in some cases as supplementary reading for the course."--Marion Deutsche Cohen, Mathematical Intelligencer "The cumulative effect of fairly simple paths to estimating solutions to a dizzying array of difficult problems is fascinating."--Ray Bert, Civil Engineering "This book will be enjoyed by anyone with an interest in estimation, but is also targeted at those applying for jobs at companies like Google, where the kind of questions considered in the book are often used in the interview process."--Paul Taylor, Mathematics TodayTable of ContentsAcknowledgments xi Preface xiii Chapter 1: How to Solve Problems 1 Chapter 2: Dealing with Large Numbers 11 2.1 Scientific Notation 11 2.2 Accuracy 14 2.3 A Note on Units 16 2.4 Unit Conversion 17 Chapter 3: General Questions 19 3.1 One big family 21 3.2 Fore! 25 3.3 This is a fine pickle you've got us into, Patty 29 3.4 Throwing in the towel 31 3.5 Hey buddy, can you fill a dome? 35 3.6 A mole of cats 39 3.7 Massive MongaMillions 41 3.8 Tons of trash 43 3.9 Mt.
