M. : Intellect Center, 2013. — 88 s. The collection contains more than 500 tasks, similar to the basic level tasks of the State final certification in mathematics in 2013, included in the updated open bank of mathematical tasks (www.) mathgia. ru), and more than 100 higher-level problems in algebra and geometry. Basic level tasks are divided into modules: algebra, geometry, real mathematics. High-level tasks are given by modules: algebra, geometry. The book gives four training options corresponding to the 2013 GIA demo.. The book will allow not only to prepare for the solution of basic level GIA tasks in all three modules, but also to consolidate the knowledge of the school course of mathematics in the learning process. Answers are given to all tasks. The collection is addressed to students of the ninth grades for preparation for GIA in mathematics . The manual will be useful to teachers, high school students, their parents, as well as Methodists.
