Collection of arithmetic problems in 1913
Recently got into the hands of "systematic collection of arithmetic problems" of the last veka.I read it as a fiction book and was amazed that in this tutorial got on the history of the country and the world, geography, astronomy, statistics, calculation of credits or loans, and even calculus convert currencies in the world. That is, doing arithmetic pupil than the ability to do the calculations to know and other nauki.Sovremennye textbook deprived of all this, some tasks that you begin to understand just by reading them pyat.I this we are adults, but what about the children? Maybe because of this textbook in our country there Tsiolkovsky, Kurchatov, Korolev and other outstanding scientists?
