The book is a comprehensive guide to mental calculations and mathematical shortcuts, designed to help readers perform complex calculations quickly and accurately without the need for a calculator or other tools. The book is divided into several sections, each covering a different aspect of mental calculation. These include addition, subtraction, multiplication, division, fractions, decimals, percentages, and square roots. Each section is presented in a clear and concise manner, with step-by-step instructions and plenty of examples to help readers understand the concepts and techniques.In addition to the practical aspects of mental calculation, Henderson's book also explores the intellectual benefits of developing this skill. The author argues that mental calculation can help improve memory, concentration, and overall cognitive function, and provides exercises and strategies for readers to practice and develop their mental abilities.Overall, Henderson's Intellectual and Practical Lightning Calculator is a valuable resource for anyone interested in mental calculation, whether for practical or intellectual reasons. The book's clear and straightforward approach makes it accessible to readers of all levels, and its timeless insights and techniques continue to be relevant and useful today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
