Request systems. More than 100 substantive tasks. Focuses, puzzles, historical facts. Solving problems from the exam in computer science. Zlatopolsky D.M.

The book contains tasks, tricks, puzzles and other fascinating materials associated with informing systems of number. Its materials can be used in lessons, as homework, on circles and electives, in extracurricular work.

The book consists of 18 chapters and contains 13 applications. It gives: tasks of different levels of complexity; Methodology for solving standard problems for the number systems presented in a single state exam in computer science; arithmetic and geometric progressions of numbers in non -native systems; logical and shift operations; The basic principles of creating the so -called "noise -resistant" codes; Mathematical tricks, puzzles, games with numbers in the short -term number systems.

All tasks presented in the book are of developing importance for intelligence, form general educational skills and contribute to increasing students' interest in mathematics and computer science. All tasks are given answers and clarifications.

The applications describe various methods (including little -known) translation from one number of intended numbers and correct fractions, programs (with the methodology for their development) of solving problems related with reckoning systems, a solution of puzzles and a demonstration of tricks examined earlier, and also presented materials of a historical nature (such materials are also available in the main part of the book in the form of a “fit”).

If you need the tasks of different levels of complexity The topic “Request systems” for lessons and homework, puzzles, tricks and games related to this topic, materials for extracurricular work and students' project activities, then this book is for you.
