Product Description

Synopsis

This volume describes techniques of computation and approximation that may be used to mentally and rapidly calculate mathematical quantities, including results of arithmetic operations and values of elementary functions. These methods range from very old to recent to brand new. They are not shortcuts, rather, the book is aimed at sharpening the mental skills needed to perform "mathematical acrobatics". The book is intended for those whose interest in mathematics has engendered a general appreciation of numbers and a desire to expand their capacities of abstract thought. It presents a set of useful and challenging methods and algorithms for quick mental computation of products, quotients, roots of non-perfect powers, and trigonometric, logarithmic and exponential values. Chapters begin with quotes from mathematicians and philosophers, such as Bertrand Russell, James Lowell and Alfred North Whitehead.

5.0 out of 5 stars The magnum opus of mental arithmetic!, 31 Jan 1999

By A Customer

Imagine transforming your mind into a slide-rule with the added bonus of extra precision! "Dead Reckoning" is the ONLY book of its kind, running the gamut from ordinary operations like multiplication and division to roots (square, higher-order, and reciprocal), logarithms and their inverses, and finally trigonometric functions and their inverses. The book also contains other gems such as factorization techniques, continued fractions (for creating rational approximations), and also an algorithm which permits mental square root extractions to arbitrary precision. Those who feel daunted by symbolic formulas needn't worry, the book is replete with examples which provide both clarity and realism to the presentation. The author has an engaging style and has obviously taken great pains; the clarity of the exposition is excellent throughout. Moreover, the text is profusely referenced for those wishing to further pursue a topic that piques their interest. The techniques and strategies contained therein are as practical as they are efficient and are equally amenable to quick pen-and-paper calculations for those not interested in pursuing mental computations. Heartily recommended! - Grant Nixon
