Shakhno. Collection of problems in elementary mathematics increased complexity. 2nd ed. 1965.526 pages djvu. 10.3 MB.
Collection contains more than a thousand problems in elementary mathematics, mainly the increased difficulty. Problem, if possible, and provided with a systematic solutions. In some cases, due to the solution of the problem and, where appropriate, are the questions of the theory. Sometimes they are preceded by the decision of the task group, united by a common idea. Clarifications on the theory of equivalence of equations, graphing, complex numbers, inverse trigonometric functions, mathematical induction, and some other issues.
