Paperback. Condizione: New. Print on Demand. This book is a complete arithmetic textbook designed for students who have mastered the elements of numbers. It combines mental and written arithmetic in a practical and philosophical manner, and it treats these subjects both analytically and inductively. The author believes that a clear comprehension of the principles of arithmetic is essential to its thorough mastery, and their induction, proof, and illustration are mental exercises of great value. Until the pupil can inductively step from processes to principles, the author believes they have not a thorough knowledge of numbers. In this book, the principles are concisely and formally stated in connection with the rules which are based upon them. The author invites special attention to the sections treating of Percentage, Ratio and Proportion, and Involution and Evolution. The author maintains that a thorough treatment of Ratio before Proportion, and of the latter before its application to the solution of problems, will make the mastery of this subject easy. The treatment of Involution and Evolution is not only full and thorough, but of great practical value. The book will prove eminently adapted to the present wants and condition of graded systems of instruction.
