An Advanced Arithmetic for High Schools, Normal Schools, and AcademiesGinn, 1898 - 400 σελίδες Every high school, normal school, and academy should allow sufficient time for a thorough review of arithmetic. This book has been written as a text-book for that purpose. The shortest and surest road to a knowledge of arithmetic is by solving problems, and these problems are designed to convey a great deal of useful information and to furnish the very best mental training, the primary object of the study. It is not necessary for any pupil, or any class to do all the problems. Every teacher can select parts of chapters, chapters, or problems suited to the needs of the pupils. |
