Book Description

Excerpt from Commercial Algebra, Vol. 2 This work has been prepared to meet the needs of advanced classes in algebra in commercial high schools. It presupposes one year's work in algebra, and while this may preferably be pursued in the study of Book I, which emphasizes the com mercial aspect of the subject as far as seems reasonable, any good course in the first year of algebra will furnish sufficient preparation for the work now in hand. The most important commercial features of the second year in this kind of algebra are compound interest and its extensive applications in modern business, equation of payments, annuities, amortization, depreciation, bond valuation, and life insurance. In order to be adequately prepared to undertake the study of these features, however, it is necessary to have a thorough working knowledge of logarithms and series. For a good understanding of logarithms it is necessary to introduce a chapter on powers and roots, and this chapter becomes, therefore, the logical point of departure for the year's work. Logarithms naturally lead to a study of the slide rule, an instrument that has recently come into very extensive use in the industrial work of this country, and which is certain to be of large service in checking computa tions in the problems of commerce.
