ARITHMETICAL OR ALGEBRAIC METHOD IN SOLVING PRIMARY SCHOOL MATHEMATICAL PROBLEMS
The purpose of the present paper is to outline the boundaries of the mathematical „cover“ of the arithmetical approaches in solving primary course mathematical problems. The paper studies the cases when classical didactic models of school arithmetics are „help...

STATIONARY NUMBERS
The article studies one method of numbers generation. For this new method we define and study sets of so called \(m\)-digitaddition and \(m\)-self positive integers. In addition, we introduce a stationary number term for the mentioned operation and provide a...

A GENERAL APPROACH TO ESTABLISH RELATIONS AMONG THE RADII OF TANGENT CIRCLES
A general idea is considered to establish relations among the radii of tangent circles in the plane of a given triangle. The idea is based on Euler’ s formula for the distance between the radii of the circum-circle and the in-circle of the triangle and also on...
