College Algebra (Lial/Hornsby/Schneider Series)

Focusing on helping students to develop both the conceptual understanding and the analytical skills necessary to experience success in mathematics, we present each mathematical topic in this text using a carefully developed learning system to actively engage students in the learning process. We have tried to address the diverse needs of today's students through a more open design, updated figures and graphs, helpful features, careful explanations of topics, and a comprehensive package of supplements and study aids. Students planning to continue their study of mathematics in calculus, trigonometry, statistics, or other disciplines, as well as those taking college algebra as their final mathematics course, will benefit from the text's student-oriented approach. We believe instructors will particularly welcome the new Annotated Instructor's Edition, which provides answers in the margin to almost all exercises, plus helpful Teaching Tips.

Times Tables the Fun Way: Book for Kids: A Picture Method of Learning the Multiplication Facts

Memorization of the multiplication facts is fun and easy with this colorful and clever book of cartoons and stories. Children learn to associate the numbers with the characters in the story. To teach 4x4, the story tells about Bart who loves to go hang gliding and can't wait until he turns 16 so he can get his driver's license and drive his 4 by 4. Children easily remember once the story is learned. The caption below the story says: Remember: you have to be 16 to drive a 4x4.

There are cartoons and stories for all the difficult facts, ie. the 3's, 4's, 6's, 7's, and 8's. Tricks are are used to teach the easier ones ie. 1's, 2's, 5's, and 9's. Kids love the stories and will never forget "You have to be 16 to drive a 4 by 4, (4x4). Over 500,000 copies have been sold to schools in the US since 1992.

Zero: The Biography of a Dangerous Idea

The seemingly impossible Zen task--writing a book about nothing--has a loophole: people have been chatting, learning, and even fighting about nothing for millennia. Zero: The Biography of a Dangerous Idea, by noted science writer Charles Seife, starts with the story of a modern battleship stopped dead in the water by a loose zero, then rewinds back to several hundred years BCE. Some empty-headed genius improved the traditional Eastern counting methods immeasurably by adding zero as a placeholder, which allowed the genesis of our still-used decimal system. It's all been uphill from there, but Seife is enthusiastic about his subject; his synthesis of math, history, and anthropology seduces the reader into a new fascination with the most troubling number.

Why did the Church reject the use of zero? How did mystics of all stripes get bent out of shape over it? Is it true that science as we know it depends on this mysterious round digit? Zero opens up these questions and lets us explore the answers and their ramifications for our oh-so-modern lives. Seife has fun with his format, too, starting with chapter 0 and finishing with an appendix titled "Make Your Own Wormhole Time Machine." (Warning: don't get your hopes up too much.) There are enough graphs and equations to scare off serious numerophobes, but the real story is in the interactions between artists, scientists, mathematicians, religious and political leaders, and the rest of us--it seems we really do have nothing in common. --Rob Lightner

A concise and appealing look at the strangest number in the universe and its continuing role as one of the great paradoxes of human thought

The Babylonians invented it, the Greeks banned it, the Hindus worshiped it, and the Church used it to fend off heretics. Now, as Y2K fever rages, it threatens a technological apocalypse. For centuries the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything.

In Zero science journalist Charles Seife follows this innocent-looking number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe, its rise and transcendence in the West, and its ever-present threat to modern physics. Here are the legendary thinkers--from Pythagoras to Newton to Heisenberg, from the Kabalists to today's astrophysicists--who have tried to understand it and whose clashes shook the foundations of philosophy, science, mathematics, and religion. Zero has pitted East against West and faith against reason, and its intransigence persists in the dark core of a black hole and the brilliant flash of the Big Bang. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for a theory of everything.

Readers of Fermat's Enigma, The Man Who Loved Only Numbers, Seeing and Believing, and Longitudewill find the revealingly illustrated Zero freshly informative, easy to understand, and--infinitely--fascinating.
