Elementary AlgebraMacmillan, 1912 - 341 σελίδες As far as the authors know, this is the first beginners' book that graphically illustrates the fundamental rules, laws and facts of algebra, and brings into bold relief those portions of it that are indispensable to the study of geometry, physics, and chemistry pursued in secondary schools. The first ten chapters furnish an easy introduction to algebra, with simple problems having natural solutions. The second ten chapters demand more of the student, while fixing principles in the mind by means of examples that move from easy, to those of increasing difficulty. |
