Book Review:
Combined Mathematics (Pure Mathematics): Simplified Presentation by Dunstan Perera is a well-crafted textbook that addresses the needs of Sri Lankan A Level students tackling the challenging subject of Combined Mathematics. Drawing on his extensive experience as a mathematics teacher, examiner, and former Director of Mathematics at the National Institute of Education, Perera presents Pure Mathematics concepts in a clear, step-by-step manner that makes complex topics more accessible. The book covers Algebra, Trigonometry, Coordinate Geometry, and Calculus with practical examples and graded exercises designed to build understanding progressively. Particularly valuable is the author's attention to bridging the gap between O Level and A Level mathematics—a challenge many students face. While the book is thorough in its coverage, its strength lies in its simplified presentation style, making it an excellent resource for students who find Pure Mathematics daunting. A recommended addition to any A Level mathematics student's library.
