A classic Russian course of algebra, taught entirely through problems.K. F. Lebedintsev (1878-1925) was one of the most influential Russian teachers of mathematics of the early twentieth century. He held that algebra should grow out of concrete problems worked by the student, not out of rules learned by heart. This collection puts that conviction into practice.Part 1 begins where algebra begins - with the passage from particular arithmetic solutions to general formulas - and leads step by step through:• negative numbers and the four operations on algebraic quantities• integral and fractional expressions, factoring, and zero and negative exponents• equations of the first degree in one, two and three unknowns, and the many word problems that lead to them• inequalities of the first degree• first-order functions and their graphs, with railway timetables, temperature records and river levels to plotMore than 1,600 problems and exercises, arranged in order of increasing difficulty within every section. The word problems are drawn from trade, travel, work, science and everyday life, and keep the historical units of the original - versts, arshins, poods, rubles and kopecks - with a short guide to them in the Translator’s Note.As the author intended, no answers are printed: the problems are designed so that students can check their own work. The collection serves equally well in the classroom, for independent study, and as a rich source of problems for teachers.English edition of Part 1: all five divisions, every problem, exercise and table.
