The textbook is intended for high school students for high -quality preparation for entrance tests in mathematics, as well as to participate in mathematical olympiads at various levels.
In the manual, equations of increased complexity related to various sections of mathematics are offered. For each of the equations, as a rule, a non -standard method for solving in the author’s interpretation is given.
The manual discusses very complex equations that are included in the school curriculum or complement it. In general, all the proposed 180 equations correspond to the level of requirements of entrance examinations in mathematics.
The manual is addressed to students of secondary schools, gymnasiums, lyceums, colleges, applicants, mathematics teachers, leaders of school mathematical circles, tutors, organizers of mathematical olympiads and teachers who make up the tasks of competitive tests upon admission to the largest universities in the Russian Federation
