PREFACE TO THE SECOND EDITION.
The special object of this Treatise is to furnish explanations of the fundamental principles of Arithmetic more full and clear than those usually given.
It should be held to be of the utmost importance that the reason of every step in every process employed should be made perfectly intelligible to the learner; if at least Arithmetic is to be looked on as an important branch of mental training, rather than a mere series of operations to be mechanically performed.
This book is consequently a protest against that still common process of teaching "sums,” which may be called the “magical process:” “Follow the rule as laid down,” says the master, “do not trouble yourself about the reason : but do this, do that, and_hey presto! the answer.”
