Mathematical Quickies by Charles W. Trigg Pdf

For the mathematics enthusiast of any age or level of sophisitcation, this stimulating treasury of unusual math problems offers unlimited opportunity for mind-biggling recreation. Carles W. Trigg, Dean Emeritus and Professor Emeritus at Los Angeles City College and one of the country's best-known problemists, has compiled nearly 300 mathematical brainteasers from the field of of arithmetic, algebra, plane and solid geometry, trigonometry, number theory, and such general recreational mathematics and dissections, cryptarithms and magic squares. The object of each problem is to find the quickest, most elegant solution - they are often unorthodox and there is usually and element of surprise in each. Ranging from the simple to complex, problems are both original with the author and the work of over 100 other qualified mathematicians. Most are rarely seen or entirely new; all challenge the reader to devise solutions more elegant than the ones provided.

Mathematical Magic Show by Martin Gardner Pdf

Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This volume, first published in 1977, contains columns published in the magazine from 1965-1968. This 1990 MAA edition contains a foreword by Persi Diaconis and Ron Graham and a postscript and extended bibliography added by Gardner for this edition.

The Singapore Mathematics Calendar 2022 (Elementary) by Yan Kow Cheong Pdf

The Singapore Mathematics Calendar is a three-book series (Elementary, Intermediate, and Advanced) that provides an informal yet creative way for both parents and homeschoolers to support their child succeed in math. This math calendar is designed so that the answer to the problem on each day is the date on which the problem appears. The daily dose of both routine and nonroutine questions aims to develop the child’s problem-solving and guesstimation skills, while exposing them to valuable mathematical information that goes beyond their textbook. Hints and solutions are also provided for nonroutine or brain-unfriendly questions. Moreover, each month begins with some elements of enrichment or recreational math to challenge or enrich the child. Through math activities, puzzles, and games, The Singapore Mathematics Calendar seeks to complement and supplement what the child is doing in school or at home, by making math fun and educational. The Singapore Mathematics Calendar hopes to convey the message that mathematics needn’t be drill-and-kill exercises—it can be fun, yet challenging for students to be exposed to the beauty and joy of mathematics.

Impossible Folding Puzzles and Other Mathematical Paradoxes by Gianni A. Sarcone,Marie-Jo Waeber Pdf

Do all problems have solutions? Is complexity synonymous with difficulty? This original collection of mathematical puzzles and paradoxes proves that things aren't always what they seem! Readers will discover that nothing is as easy or as difficult as it looks and that puzzles can have one, several, or no solutions. The fun-filled puzzles begin with The Tricky Hole, a challenge that involves pushing a large coin through a small hole in a sheet of paper without ripping or making any cuts in the paper. Advance to the Elastic Playing Card, in which it's possible to cut a hole into a playing card big enough for someone to climb through. Other incredible puzzles include Elephants and Castles, Trianglized Kangaroo, Honest Dice and Logic Dice, Mind-reading Powers, and dozens more. Complete solutions explain the mathematical realities behind the fantastic-sounding challenges.
