Collection of Problems in Algebra. Grades 7-9

The manual contains problems from all sections of algebra studied in grades 7-9. The problems are divided into three levels of difficulty. The first level includes elementary problems, the second level comprises basic problems, and the third level consists of... more complex problems, including Olympiad and competition problems. This allows the collection to be used both for classroom lessons and for preparing students for subject Olympiads and the State Final Attestation (GIA). Answers are provided for all problems, and methodological guidelines are given for the most difficult ones. It is intended for teachers and students of general and specialized schools.
