This book is about playing with mathematics, teaching: (1) How to multiply and divide large numbers mentally; (2) Making addition and subtraction easy; (3) Tricks for understanding fractions and decimals; and (4) How to quickly check answers for each calculation. Described as a foolproof way to do multiplication, division, factoring estimating,…

Since all manner of quantities require to be compared together, in mathematical computations, and their various relations searched out and determined and as most of our knowledge in mathematical subjects depends on the proportions of several things to one another: so it is requisite that the nature of proportion, and the methods of reasoning…

This arithmetic textbook aims to teach the reading of figures so as to train the mind to instantly catch the idea that any combination of figures is intended to express. This is to be done by "the simple process of reading;" and the method consists: (1) in teaching the alphabet; and (2) in teaching the combinations of the alphabet, which…

Arithmetic is the science of numbers, and also the art of computation. This textbook presents mental and written arithmetic through simple numbers. [This book was written by the Brothers of the Christian Schools and published by De La Salle Institute.]

There is offered in this book a year's work in numbers for those boys and girls who know one to ten thoroughly. The book is designed for the children themselves. The practical use of this text in various schools for several years gives evidence by its success that as soon as children can read they should have arithmetics in their hands. [Cover…

This textbook provides the foundation for a course in mathematics covering arithmetic, algebra, geometry, conic sections, and arithmetic of infinites. An appendix on practical gauging is included, as well as a supplement containing the history of logarithms. [This edition was corrected and improved by Samuel Clark.]

This textbook is an introductory mathematics course. It is a treatise of arithmetic, containing all the practical parts thereof; both in whole numbers, vulgar fractions, and decimals; likewise the theory of numbers, and their principal properties, demonstrated in a plain and easy manner.

This arithmetic textbook uses small concrete numbers to lead pupils to understanding numbers' properties and relations. This work is intended as a connecting link between the Primary and Written Arithmetics of the Author. It presents a mental analysis of Arithmetic adapted to the younger pupils by its easy gradations, and to advanced pupils by its…

This textbook is a course in mental arithmetic that is essentially based on the object-lesson plan. It is believed that the pupil in the primary school can more readily acquire a familiarity with numbers from the use of objects and pictures than from an uninterrupted drill on the tables. It also includes suggestions for teachers how to use the…

This textbook aims to present the mathematical sciences in clear, everyday language for apprentices, students and mechanics--willing, industrious, anxious to study at home, yet unable to give time or money for professional teaching. It is trusted that this effort to place before English-speaking students a treatise on arithmetic and algebra, freed…

For boys and girls who are prepared in the essential elements of arithmetic this later book proposes extended instruction in percentage and commercial transactions, and in the elements of geometry. It is one of a series of handbooks for pupils, and consists of progressive lessons, arranged mainly in topics, either reviewing the treatment in…

For boys and girls who are prepared in the essential elements of arithmetic this, the Fifth Book of the Series, proposes additional instruction in concrete measurements, percentage, interest, and commercial matters. This Series purports to be only a systematic arrangement of lessons for children studying the subject. It consists of graded lessons…

This textbook is part two of an arithmetic course. It provides systematic drill on oral and written exercises, and review and test questions. Attention is invited to the properties of numbers, greatest common divisor, fractions, decimals, compound numbers, business arithmetic, ratio and proportion, alligation, and square and cube root, with the…

This textbook is an illustrated table book rather than an elementary arithmetic book. Its object is to suggest things for pupils to do. While it is impossible in a work so small to do more than give suggestions, the teacher will find little difficulty in supplying the deficiency by the use of the blackboard. Although there is nothing in the book…
