Excerpt from Elementary Algebra: First Year Course In this book algebra is presented to beginners in a simpler, clearer, and more practical form than is usually found in school texts. The treatment is simplified by the omission of certain redundant terms and notations, by maintaining an intimate connection between algebra and arithmetic, and by starting with definite assumptions of the laws of signs in subtraction and multiplication rather than with complicated and unsatisfactory proofs. The part of algebra that deals with the P-mechanical manipulation of algebraic expressions is reduced in amount as much as is consistent with the acquirement of accuracy. Simple fractions and easy radicals are introduced early; the discussion of fractions with binomial and trinomial denominators, and consideration of the more difficult parts of radicals, are postponed to a time near the close of the course. n, Ratio and proportion are brought into closer touch with the equation and with graphs. Clearness has been sought by careful definition, copious illustration, and by the use of language which recalls the axiomatic processes involved. Such phrases as "clearing of fractions" are objectionable because of the danger of their, being applied by the pupil, not to the equation alone, but to algebraic expressions in general. "Canceling," as now used, is ambiguous, for it sometimes involves subtraction, at other times division. The treatment is rendered more practical by a careful selection of problems.
