THE object of the series of text-books of which Advanced Arithmetic is a part is threefold :
I. To secure accuracy and facility in the mechanics of number. To accomplish this result there is a continuous presentation of the fundamental processes with integers and with fractions, both common and decimal.
II. To relate the use of number to the affairs of everyday life.
This requires the solution of problems in household and school economics, in the affairs of the playground, the workshop, and the farm, and a study of conditions existing in the business world.
III. To develop a power of insight and analysis which shall render pupils resourceful and self-reliant. This involves the introduction of many problems requiring the use of more than a single process in their solution, and drawn from a great variety of sources, both within and without the experience of the pupil. A foundation is thus laid for work in mathematics beyond grammar school grades.
Some subjects ordinarily included in grammar school courses are purposely omitted because it is believed that the mastery of a few subjects is the sane and wise method of procedure in the development of mathematical power. Quality, not quantity, of work is of prime importance in training young pupils.
The subject matter of Advanced Arithmetic is so arranged that pupils leaving school before the completion of the regular course are given opportunity to acquire some knowledge of practical business methods.
The author wishes to acknowledge his indebtedness to all who have assisted in the preparation of the manuscript, and especially to Mr. Myron T. Pritchard, Master of the Everett School, Boston, Massachusetts, for wise counsel and criticism.
