Can you multiply 362 x .5 quickly in your head? Could you readily calculate the square of 41? How much is 635 divided by 2«? Can 727,648 be evenly divided by 8? If any of these questions took you more than a few seconds to solve, you need this book. Short-Cut Math is a concise, remarkably clear compendium of about 150 math short-cuts ? timesaving tricks that provide faster, easier ways to add, subtract, multiply, and divide. By using the simple foolproof methods in this volume, you can double or triple your calculation speed ? even if you always hated math in school. Here's a sampling of the amazingly effective techniques you will learn in minutes: Adding by 10 Groups; No-Carry Addition; Subtraction Without Borrowing; Multiplying by Aliquot Parts; Test for Divisibility by Odd and Even Numbers; Simplifying Dividends and Divisors; Fastest Way to Add or Subtract Any Pair of Fractions; Multiplying and Dividing with Mixed Numbers, and more. The short-cuts in this book require no special math ability. If you can do ordinary arithmetic, you will have no trouble with these methods. There are no complicated formulas or unfamiliar jargon ? no long drills or exercises. For each problem, the author provides an explanation of the method and a step-by-step solution. Then the short-cut is applied, with a proof and an explanation of why it works. Students, teachers, businesspeople, accountants, bank tellers, check-out clerks ? anyone who uses numbers and wishes to increase his or her speed and arithmetical agility, can benefit from the clear, easy-to-follow techniques given here.

Geometric Constructions

Geometric constructions have been a popular part of mathematics throughout history. The first chapter here is informal and starts from scratch, introducing all the geometric constructions from high school that have been forgotten or were never learned. The second chapter formalises Plato's game, and examines problems from antiquity such as the impossibility of trisecting an arbitrary angle. After that, variations on Plato's theme are explored: using only a ruler, a compass, toothpicks, a ruler and dividers, a marked rule, or a tomahawk, ending in a chapter on geometric constructions by paperfolding. The author writes in a charming style and nicely intersperses history and philosophy within the mathematics, teaching a little geometry and a little algebra along the way. This is as much an algebra book as it is a geometry book, yet since all the algebra and geometry needed is developed within the text, very little mathematical background is required. This text has been class tested for several semesters with a master's level class for secondary teachers.

Alchemy is thought to have originated over 2000 years ago in Hellenic Egypt, the result of three converging streams: Greek philosophy, Egyptian technology and the mysticism of Middle Eastern religions. Its heyday was from about 800 A.D. to the middle of the seventeenth century, and its practitioners ranged from kings, popes, and emperors to minor clergy, parish clerks, smiths, dyers, and tinkers. Even such accomplished men as Roger Bacon, Thomas Aquinas, Sir Thomas Browne and Isaac Newton took an interest in alchemical matters. In its search for the "Philosopher's Stone" that would transmute base metals into silver and gold, alchemy took on many philosophical, religious and mystical overtones. These and many other facets of alchemy are explored with enormous insight and erudition in this classic work. E. J. Holmyard, a noted scholar in the field, begins with the alchemists of ancient Greece and China and goes on to discuss alchemical apparatus, Islamic and early Western alchemy; signs, symbols, and secret terms; Paracelsus; English, Scottish and French alchemists; Helvetius, Price, and Semler, and much more. Ranging over two millennia of alchemical history, Mr. Holmyard shows how, like astrology and witchcraft, alchemy was an integral part of the pre-scientific moral order, arousing the cupidity of princes, the blind fear of mobs and the intellectual curiosity of learned men. Eventually, however, with the advent and ascension of the scientific method, the hopes and ideas of the alchemists faded to the status of "pseudo-science." That transformation, as well as alchemy's undeniable role as a precursor of modern chemistry, are brilliantly illuminated in this book. Students of alchemy, chemistry, the history of science, and the occult, plus anyone interested in the origin and evolution of one of mankind's most enduring and influential myths, will want to have a copy of this masterly study.
