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.

The subject is used starting from daily life to advanced scientific field. Over the generation mathematics has become the language of science & played immense role in advancing human culture. The subject is integral part of school curriculum still many student find the subject difficult. No matter how hard we try , we can't run away from at least basic mathematics. Because it requires in almost all business. The math develops logical , rational thinking. Its not only just solving problem but it is the way to deal with unknown situation use the resource , knowledge at our hand. To master this subject, conceptual study is required. But most of time student run behind thousands of shortcut. Shortcuts varies from problem to problem. Hence by such approach to master in subject one has to remember thousands of unnecessary shortcuts. Its is stressful & often decreases accuracy. So instead of learning thousands shortcuts , its better to understand subject logically, conceptually. Such one time learning give advantages to student lifetime. This book gives generic concept by using which one can solve problem faster than shortcuts. Since ,methods are generic. So they are limited. Many methods in this books are the result of deep insight, understanding research in subject & they are not available elsewhere. Editing this book was quite hectic process. The different colours are added to make explanation easy to understand. ------------------------------------------------------------- LEARN MATHEMATICS ONE TIME | REMEMBER LIFE TIME || ------------------------------------------------------------------- SALIENT FEATURE ------------------------------------------------------------------ o Uses clear, easy language to understand o Explain subject with unified, coherent approach o Simplifies quicker methods of Vedic Mathematics o Goes from basic to advance level o Gives quicker method for all topics that include Multiplication, Division, Power & roots, Equation, LCM -HCF etc. o Effective use of different colors to simplify lesson, to emphasize essential concept. o Present novel methods invented by authors for topics like Divisibility checking, Higher power & roots, Squaring etc. o Useful for competitive exams to solve problems instantaneously

This book is only about numbers - that is, whole numbers and nothing but the whole numbers, which start from from 0, 1, 2, 3, 4... and go on forever. Here you can meet perfect numbers, happy numbers, lucky, untouchable, weird, narcissistic, evil and deficient numbers, not to mention nice Friedmans and multi-legged repunits, as well as primes and their cousins, the sexy primes. It is also full of fascinating facts and curios, prime number conjectures, the sieve of Eratosthenes, the Fibonacci series, and much more besides. This is an accessible, clearly explained approach which will appeal to recreational maths enthusiasts, puzzle solvers, and mathematicians of all ages.

We hear all the time how American children are falling behind their global peers in various basic subjects, but particularly in math. Is it our fear of math that constrains us? Or our inability to understand math’s place in relation to our everyday lives? How can we help our children better understand the basics of arithmetic if we’re not really sure we understand them ourselves? Here, G. Arnell Williams helps parents and teachers explore the world of math that their elementary school children are learning. Taking readers on a tour of the history of arithmetic, and its growth into the subject we know it to be today, Williams explores the beauty and relevance of mathematics by focusing on the great conceptual depth and genius already inherent in the elementary mathematics familiar to us all, and by connecting it to other well-known areas such as language and the conceptual aspects of everyday life. The result is a book that will help you to better explain mathematics to your children. For those already well versed in these areas, the book offers a tour of the great conceptual and historical facts and assumptions that most simply take for granted. If you are someone who has always struggled with mathematics either because you couldn’t do it or because you never really understood why the rules are the way they are, if you were irritated with the way it was taught to you with the emphasis being only on learning the rules and “recipes” by rote as opposed to obtaining a good conceptual understanding, then How Math Works is for you!

Special topic volume with invited peer reviewed papers only

Since the first edition of this book was published, there have been major improve- TM TM ments in symbolic mathematical languages such as Maple and Mathematica and this has opened up the possibility of solving considerably more complex and hence interesting and realistic elasticity problems as classroomexamples. It also enables the student to focus on the formulation of the problem (e. g. the appropriate governing equations and boundary conditions) rather than on the algebraic manipulations, with a consequent improvement in insight into the subject and in motivation. During the past 10 years I have developed files in Maple and Mathematica to facilitate this p- cess, notably electronic versions of the Tables in the present Chapters 19 and 20 and of the recurrence relations for generating spherical harmonics. One purpose of this new edition is to make this electronic material available to the reader through the Kluwer website www. elasticity. org. I hope that readers will make use of this resource and report back to me any aspects of the electronic material that could benefit from improvement or extension. Some hints about the use of this material are contained in Appendix A. Those who have never used Maple or Mathematica will find that it takes only a few hours of trial and error to learn how to write programs to solve boundary value problems in elasticity.

This publication focuses on the critical methods that can be used to dramatically improve the fiscal closing process. The Record to Report (R2R) or Fiscal Closing Process is at the core of the controllership function. The process includes transaction processing, internal and external reporting, and the internal controls—the people, processes, and technology—that constitute the corporate organizational hierarchy. CFOs, controllers, and corporate finance departments require timely, accurate, and consistent data to make appropriate operational and strategic decisions and fulfill statutory, regulatory, and compliance requirements with accurate and timely data. The Fast Close Toolkit offers both strategic and tactical suggestions that can significantly improve the fiscal closing process and provides guidance on new legislation requirements, systems and best practice processes. Checklists, templates, process narratives, and sample policies are provided for every component of the fiscal close. Investors and shareholders expect fast and easy access to the data created by current business activities in the information-driven digital age. The Fast Close Toolkit provides the necessary tools and expert advice to improve the fiscal closing process. Authoritative and up to date, this book: Identifies the bottlenecks that can impact the and improvethe fiscal close process and provides best practices to help alleviate these challenges Defines the Record to Report (R2R) and recommends the roles and responsibilities for fiscal close processes flow Offers the internal controls to use for the end-to-end fiscal close process Describes approaches for risk management, R2R, and fiscal close benchmarking Identifies KPIs for all aspects of the R2R process Provides the mechanism for developing a financial close scorecard Recommends leading practices for both external and internal reporting Provides guidance on how strategic planning, the budget and forecast processes can be streamlined to enhance the fiscal close and internal reporting results Written by a respected expert on internal controls and the fiscal closing process, The Fast Close Toolkit is a valuable source of information for professionals involved in controllership and have responsibility for the fiscal close.
