Finalist of the 2022 PROSE Awards How fast can you calculate? Would you like to be faster? This book presents the time honored tricks and tips of calculation, from a fresh perspective, to boost the speed at which you can add -- whether a couple of numbers, or columns so long an accountant may faint. Find out how to subtract, multiply, divide, and find square roots more quickly. What's more, this book gives suggestions for how to find answers that are good enough for tricky tasks like dividing by 17. It includes brand new ways to multiply and divide irrational numbers such as pi, e, the square root of 2, and the golden ratio. It has sections devoted to ancient mathematics, and the techniques we can borrow from previous and other cultures, in order to calculate more quickly. Examples, some serious, some fun, come from everyday life or from history -- like hot dog eating competitions, the Vatican's cricket team, the molecular weight of the molecule with the world's longest name, and the amount of people taken by Henry VIII to arguably history's biggest party, the Field of the Cloth of Gold. In an age of timed multiple-choice questions, the swifter you can sum, or rule out wrong answers, the better you will do. If you love to play with numbers, this book will be recreational reading. And if you ever wonder whether simple arithmetic problems can crop up in everyday life, this book provides a fresh perspective.

Demonstrates a slew of time-saving tips and tricks for performing common math calculations. Contains sample problems for each trick, leading the reader through step-by-step. Features two mid-terms and a final exam to test your progress plus hundreds of exercise problems ranging from simple to more sophisticated. Also includes sections on ``Mathematical Curiosities'' and ``Parlor Tricks'' for math lovers.

Respiratory Care Calculations, Fourth Edition Revised prepares students to calculate those equations correctly, and then interpret that data in a meaningful way. The end result is patients benefiting from accurate answers and appropriate applications of data.

Retaining the successful previous editions' programmed instructional format, this book improves and updates an authoritative textbook to keep pace with compounding trends and calculations – addressing real-world calculations pharmacists perform and allowing students to learn at their own pace through examples. Connects well with the current emphasis on self-paced and active learning in pharmacy schools Adds a new chapter dedicated to practical calculations used in contemporary compounding, new appendices, and solutions and answers for all problems Maintains value for teaching pharmacy students the principles while also serving as a reference for review by students in preparation for licensure exams Rearranges chapters and rewrites topics of the previous edition, making its content ideal to be used as the primary textbook in a typical dosage calculations course for any health care professional Reviews of the prior edition: "...a well-structured approach to the topic..." (Drug Development and Industrial Pharmacy) and "...a perfectly organized manual that serves as a expert guide..." (Electric Review)

Rapid calculation of the radiant power and the quantum flux emitted by a blackbody source involving any wavelength interval is made possible by the derivations in this paper which introduces the 'normalized cumulative blackbody functions' formulated by the author. Thus, in contrast to conventional blackbody tables, all different radiation temperatures and any wavelength interval are covered by one function which can be compiled in one simple table of very modest volume. The final expressions using these cumulative blackbody functions are uncomplicated equations which can be solved by slide rule operations or, for higher accuracy, by using a desk calculator. Further, the paper introduces an unambiguous symbolism for expressing power and quantum flux radiated by a blackbody source and for expressing performance factors such as conversion yields of broadband radiation detectors. Also equations for calculating the difference in power and quantum flux for blackbody sources against a blackbody background are derived. Illustrative examples for typical situations are calculated.
