Was born in Pskov. Graduated from Petrograd University (1915), professor (1934), doctor of pedagogical sciences (1957). In 1920-1959 worked at the Tver Institute of Public Education (now the Kalinin Pedagogical Institute). Since 1959, after retirement, supervised graduate students, in 1965-1971. was a consulting professor. The main works of Bradis are devoted to the theoretical and methodological development of issues of increasing the computational culture of high school students. His "Methodology for Teaching Mathematics in High School" has been reprinted many times and translated into other languages. In 1921 his "Tables of four-digit logarithms and natural trigonometric quantities" were published for the first time. Honored Scientist of the RSFSR (1957). Medal to them. K. D. Ushinsky. Foreword for the teacher: This small textbook is a revision of the first and KNEC Four Figure Maths Tables 7th Edition (KLB) by KLB  second editions of the book, published under the same title in the series "Working library in mathematics for grade II schools" edited by A.M. Voronets in three issues. Issue I (first edition in 1929, reprints in 1930 and 1932) contained material on approximate calculations in the fifth year of study; Issue II (first edition in 1931, reprinted in 1932) - various additional information about computing work in the sixth, seventh, eighth years of study; Issue 111 (1934) - about calculations using a table of logarithms and a counting slide rule. This publication is intended for students in grades V and VI and contains mainly the simplest information on approximate calculations, which allows solving those arithmetic problems of a practical nature with the least expenditure of time and effort, in which the data are not selected artificially in order to simplify the necessary calculations ... Foreword: In writing this book, the author had two goals. First, it was necessary to give an account of the main ideas of science of the methodology of teaching mathematics, highlighting its fundamental issues, indicating its various trends, if necessary touching on both mathematics itself and its history. Designing the book for students of physics and mathematics faculties of pedagogical institutes, the author assumed the reader's knowledge of those mathematical disciplines that are studied in the first and second years, not to mention the course of elementary mathematics studied in secondary school. Secondly, in the book, intended for students, future teachers of mathematics, it was impossible not to devote a lot of space to those questions that inevitably arise before a young Soviet high school teacher, who is called upon to teach mathematics in those specific conditions in terms of the curriculum, program, textbooks. which we currently have. The novice teacher is interested in the question of how best to carry out the work according to the current program and according to the textbooks adopted in our school, and the author believed that the teacher should be helped in this regard, that the book on the methodology should also be a practical guide, although there is a danger, that such a manual can quickly become outdated, as the country is intensively working to improve the programs and update the textbooks used. Bearing in mind the work on the current mathematics curriculum for secondary schools and on the textbooks currently adopted, the author considered it expedient to point out the possibility of introducing some innovations, already tested by the experience of individual teachers ... From the preface: This book is written on the basis of the lectures that the author gave for a number of years on a special course in elementary mathematics at the Kalinin State Pedagogical Institute named after M.I. Kalinin, but he subjected them to significant revision after consulting with a professor at the Moscow Regional Pedagogical Institute I.K. Andronov, on whose advice significant changes were made both to the plan of the book and to the coverage of many details. The first paragraph of the first chapter was written in full by I.K. Andronov. Bearing in mind the needs of the mathematics teacher of the Soviet high school, the author set himself the goal of providing everything that is necessary for understanding the theoretical foundations of arithmetic as the first section of the school mathematics https://jiji.co.ke/kitengela/books-and-games/knec-four-figure-maths-tables-7th-edition-klb-by-klb-kRYmGyHvXonc6X7CDBK1yhDt.html
