This is an automatically translated description

The first part, Exercises, is divided into three similar versions of 178 problems each (problems with the same number are of the same type). This material is primarily intended for independent tests. The presence of two more similar problems for each type of problem allows you to also use this material to practice solving the main types of problems. On pages 4, 5, you will find a table of the thematic distribution of the exercises . The tasks can be divided into two parts by content. The first part corresponds to the primary and secondary levels of pupils' learning. Tasks in this part are marked with the symbol l° (l is the number of the task). The second part corresponds to the sufficient and high levels. The tasks of each of these levels are marked with the symbols p and p*, respectively. The tasks in the first part are worth a maximum of 6 points. Correctly solved problems of the sufficient level (l*) add another 4 points, that is, the student has the opportunity to get an excellent mark of 10 points. If a student also manages to solve the l* problem, he or she receives a score of 12 points.

The manual does not have an Answers section. This is done so that you can use the manual as a handout for control and test papers.
