Hall and Knight was undertaken in the hope of being able to give to our advanced secondary schools a work that would fully meet their requirements in this important study. Many changes were made and additional subject-matter introduced. The Algebra for Beginners, however, so fully meets the needs of the class of students for which it was written, that we have made only such changes as seemed to bring out more clearly important points, and better adapt it to American schools.
With reference to the arrangement of topics, we quote from Messrs. Hall and Knight's preface to a former edition :

By this course the beginner soon
