Excerpt from Elementary Lessons in Algebra: A Text-Book for Grammar Schools

IT is believed that the time has come for the introduction of the study of Algebra into Grammar Schools. The ele mentary processes of Algebra follow so closely the funda mental processes of Arithmetic, that the teaching of both in the grammar grades is at once rational and feasible. New text-books, especially adapted to this purpose, are, therefore, necessitated. Such books should consist of series of elementary lessons, inculcating a thorough knowl edge of algebraic processes and giving facility in the use of algebraic symbols.

Elementary Lessons in Algebra aims to fulfil such a demand. The Introductory Lessons set simply, but accu rately, before the learner, the combinations of literal quan tities into sums, differences, products, and quotients, with little reference to arithmetical processes, and without associating number values to the letters often a source of confusion to the beginner, who, for the first time, meets with the use of letters as symbols. The fundamental pro cesses are placed after Simple Equations; and Equations containing Two Unknown Quantities involving Elimina tion, follow Multiplication. This sequence is believed to be more logical than placing the fundamental processes after Equations of Two Unknown Quantities, Elimination being in that case a merely mechanical process to the pupil. The treatment of Factoring is particularly full, as its importance demands.
