We solve problems in mathematics to find proportions and interest, perimeters and area of ​​figures. 5-6 cl

The book is addressed to schoolchildren in grades 5-6, their caring parents and teachers. In it, in detail, with examples and explanations, examples and tasks of the school course of mathematics are dismantled. Topics of the school curriculum, which are reflected in the book: proportions and tasks that are solved with the help of proportions, tasks for joint work, interest, simple and complex percentage growth, negative numbers, actions with negative numbers, solving equations with negative numbers, tasks for calculating the perimeter And the areas of figures, arithmetic mean, tasks for combinatorics - counting options.
In each section, tasks of increased complexity are proposed. There are answers to all tasks and exercises
