"Following up on their previous book, U.S.A. Through the Lens of Mathematics, the authors offer interesting information about all countries in the world, their history, geography, language, culture, and resources presented in the form of mathematical problems. The problems are combined in sections based on related mathematical concepts, including systems of linear algebraic equations, extremum of a function, sequencies, logical problems, and others. This fascinating book exposes students to a novel educational strategy that aims to overcome fear of mathematics, reduce mathematical anxiety, and show the applicability of mathematics to everyday life and events. The book offers interesting information about all countries in the world, their history, geography, language, culture, and resources are presented in the form of mathematical problems.
