It contains exceptional study material for those entering colleges, vocational schools etc., which can also be useful at school level, and the knowledge of it in many competitive exams. The material in part I is presented in a new form. It contains speed calculations by various methods. The methods described will provide the reader faster and easier ways to add, subtract, multiply, divide and take square roots etc. One can apply them at home or at business, to save time. These methods require no special ability in mathematics. If you can do ordinary mathematics, there will be no trouble in using these methods. The material in Part II is about numbers. The beauty of pyramid numbers and triangular numbers and some special numbers are in this part of the book. In quick to quicker multiplication many methods have been described to the masses by mathematicians. In part III, a collection of familiar puzzles in the form of geometric figures and mental ability questions is made. It also contains certain special geometric and algebraic problems." (jacket). …

Hardcover. Condizione: New. Condizione sovraccoperta: New. 1st Edition. Contents: Preface. Introduction. 1. Addition. 2. Subtraction. 3. Multiplying on an Abacus. 4. Division techniques. Exercises. The abacus is basically mechanically aided tool used for counting and forming basic arithmetic; though it is not a calculator it is a kind of calculator, similar to the four function calculators that are used in many elementary school classrooms. Whatever is available for written arithmetic can be solved by abacus. It is a light weight, easy to operate on and has the following features: It has a vivid structure, an order of digits, free parallel arrangement of bead-codes and easy variety of numbers. The number is expressed with beads moving. Addition and subtraction are connected to each other. The four fundamental operations are in close connection and interchange, with clear arithmetic principles. It is easy for the beginner to learn. The notation system that each rod stands for a definite digit and each bead counter, a specific number, leaves no doubt whatsoever even in the mind of the very beginner. More briefly explained, the Abacus is an instrument to augment mental arithmetic. The mechanics of its use is simple, and its accuracy is assured by repetition and practice alone.…
