Ready to exercise those brain cells? These 24 lectures celebrate the sheer joy of mathematics, taught by a mathematician who is literally a magician with numbers. Throughout these lectures, award-winning professor Arthur T. Benjamin shows how the beautiful and often imposing edifice that has given us algebra, geometry, trigonometry, calculus, probability, and so much else is based on nothing more than fooling around with numbers. Combining entertaining number tricks with the deeper properties of mathematics, Professor Benjamin introduces you to prime numbers, Fibonacci numbers, and infinite series. You'll investigate the powerful techniques for manipulating numbers using algebra, geometry, trigonometry, calculus, and probability in lectures that may hark back to subjects you studied in high school and college. And you'll find these lectures both a useful refresher and a bird's-eye view of the most important areas of mathematics. These lectures are especially well suited for: anyone attracted by the promise of a joyful attitude to an often-imposing subject; anyone for whom high school and college math courses are a distant memory; anyone now taking math who would like a big-picture perspective on the major areas of the field; and budding math mavens who love numbers and the magic that can be done with them. Be prepared to encounter strange equations, novel ways of thinking, and symbols and computational methods that may be new to you. But also prepare to sharpen your wits in ways you never thought possible.
