Publisher's Synopsis
Excerpt from Elementary Algebra
The book further differs from its predecessors (1) in the attention given to negative quantities and to the formal laws of algebra, known as the Commutative, the Associa tive, the Distributive, and the Index laws. In presenting these laws the author has endeavored to be rigorous without sacrificing simplicity. (2) In the fuller development of factoring and in its more extensive application to the solu tion of equations. The method of solving quadratic equa tions has been based entirely on the principles of factoring. Certainly this method is more in harmony with the pro cesses of advanced algebra, and it is the author's experience that, even for the beginner, it is quite as simple as the method of completing the square.
