Hundreds of meticulously crafted mathematical problems and puzzles in this book are incorporated into fascinating stories about our world.These wor(l)d problems are grouped by their mathematical concepts such that the titles of sections and chapters combine both mathematical and applied terms, hinting at the topics covered.Detailed solutions conclude each section. Following in the success of the authors’ previous book, USA Through the Lens of Mathematics, this text contributes to the novel pedagogical call for a more multidisciplinary approach in education.The various types of questions posed in The World through the Lens of Mathematics are stimulating, entertaining, and educational.Their main objective is to provide a thorough review of the fundamental concepts of algebra and geometry, reduce mathematical anxiety, and emphasize the applicability and versatility of mathematics.Working these problems shatters the barriers between the students and mathematics by encouraging them to look at the subject from a different perspective.Students are simultaneously enriched with new knowledge of historical events, customs, and geography of countries around the world, each one of which is mentioned throughout the pages of this book.
