How to Calculate Quickly is a tried and true method for helping you with the mathematics of daily life — addition, subtraction, multiplication, division, and fractions.
The author can awaken for you a faculty that is surprisingly dormant in accountants, engineers, scientists, businesspeople, and others who work with figures. This is "number sense" — the ability to recognize relations between numbers considered as whole quantities. Lack of this number sense makes it entirely possible for a scientist to be proficient in higher mathematics, but get bogged down in the arithmetic of everyday life.
This book teaches the necessary mathematical techniques that schools neglect to teach: horizontal addition, left-to-right multiplication, division, etc. You will learn a method of multiplication so rapidly that you'll be able to do products in not much more time than it would take to write the problem down on paper.
This is not a collection of tricks that work in only a very few special cases, but a serious, capably planned course in basic mathematics for self-instruction. It contains over 9,000 short problems and their solutions for you to work on during your spare moments. Five or ten minutes spent daily on this book will, within ten weeks, give you a number sense that will double or triple your calculation speed.
- A TRULY COMPLETE COURSE IN SPEED ARITHMETIC — This book provides a comprehensive guide to help you quickly and easily solve mathematics problems. You'll learn techniques for addition, subtraction, multiplication, division, and fractions—all of which will help awaken your "number sense." With this number sense, you'll be able to calculate at lightning speed!
- GET "NUMBER SENSE"— “Number sense” refers to the ability to recognize relationships between whole numbers. With this knowledge and the shortcuts provided, such as horizontal addition, left-to-right multiplication, division, etc., you’ll be able to solve difficult math problems with ease.
- TRAINING FOR SPARE MINUTES — Tackle problems during spare moments throughout the day. Apply just 5 or 10 minutes of your time and see your skills improve rapidly. By working through the 9,000 short problems and solutions in this book, you'll be able to make those difficult math problems a breeze!
