Arithmetic.

Practical series, freshly written, attractive, carefully graded, standard works.  They state principles and definitions clearly and simply, and provide plenty of practice.

MILNE’S NEW ARITHMETICS: 

  Elements of Arithmetic 30 cents
  Standard Arithmetic 65 cents

These books constitute an entirely new two-book series, embodying what is considered the best in modern methods of teaching arithmetic.  It is a philosophical, original, progressive, and thoroughly modern course.  The Standard Arithmetic provides a thorough and systematic training of pupils to rapidity and accuracy, while at the same time it aims to help their analytical powers and reasoning faculties.  Business processes are introduced in such a way as to render them of the greatest practical value.  Other features are a new order and arrangement of subjects; lucidity of explanations; brevity and accuracy of definitions, principles, and rules.
