First, find a shortcut solution to a classic word problem in algebra. This introduces the episode's theme: forget your algebra and use cleverness to solve problems without x's and y's. Along the way, you'll learn that sometimes having too much information can make a problem harder. Also find out why transcontinental flights take longer in one direction than the other (not counting wind effects).

Test your wits against the puzzle that likely inspired the famous expression "thinking outside the box." Then apply this strategy to a variety of brain teasers, involving matchsticks, cards, light switches, and other objects in interesting and puzzling situations. Also ponder the legendary physics exam question: How can you find the height of a building by using a barometer?

Think you've got math all figured out? Think again! Young readers can discover the wacky, weird and incredible side of math with this hands-on, inspirational and accessible guide, written by award-winning author Anna Claybourne. This book will show children math from a completely new angle - and we're not just talking about geometry! Inside you will find genius number tricks, secret shortcuts, impossible shapes, cool codes and awesome experiments....

Take up algorithmic puzzles, which require a carefully thought-out procedure (or algorithm) to solve. Algorithms have notable applications in computer science, but they also come in handy for dividing pirate gold, transporting hungry animals to an island, and solving life-or-death riddles posed by movie villains. At least, that's the entertaining approach you take in this final episode.

Finish your study of logic with puzzles where you must draw conclusions based on what other people can infer from information they are given. Your first example is the "muddy children" puzzle, in which children with muddy faces must conclude with logical certainty (without looking in a mirror, feeling their faces, or being told) that they have muddy faces. Such puzzles are unusually subtle.

Return to the Island of Knights and Knaves to consider puzzles where asking the right questions is the point of the problem. Work your way up to the famous "heaven or hell" puzzle. Then close with an exercise in coercive logic, devised by noted mathematician and puzzle master Raymond Smullyan. Easy riches hinge on a very simple bargain that sounds too good to be true. Do you accept?

Learn about biconditional statements of the form, "p if and only if q." Then tackle the "Hardest Logic Puzzle Ever," devised by philosopher George Boolos. You have three yes/no questions to identify three gods: the god who always answers truthfully, the god who always lies, and the god who randomly mixes true and false answers. One big problem: They answer in a language you don't speak.

Zero and infinity. These seemingly opposite, obvious and indispensable concepts are relatively recent human inventions. Discover the surprising story of how these key concepts that revolutionized mathematics came to be—not just once, but over and over again as different cultures invented and re-invented them across thousands of years.

La plupart des mathématiques sont présentées dans ce livre, en partant des concepts de base et élémentaires pour explorer les domaines les plus complexes et avancés.Les mathématiques sont abordées à la fois d'un point de vue théorique, en exposant des théorèmes et des définitions de chaque type particulier, et sur le plan pratique, en résolvant plus de 1 000 exercices.L'approche des mathématiques est donnée par des connaissances progressives,...
