Book Review:
Combined Mathematics (Applied Mathematics): Simplified Presentation by Dunstan Perera is an excellent companion volume to his highly regarded textbook on Pure Mathematics. Designed specifically for Sri Lankan A Level students, this book tackles the often-challenging subject of Applied Mathematics with clarity and practicality.

Drawing on his extensive experience as a mathematics teacher, examiner, and former Director of Mathematics at the National Institute of Education, Perera presents the core areas of Applied Mathematics—Statics, Dynamics, Probability, and Statistics—in a step-by-step manner that makes complex concepts accessible. Each chapter includes practical examples and graded exercises that progressively build understanding, helping students bridge the gap between O Level and A Level mathematics.

What makes this textbook particularly valuable is its focus on simplification without sacrificing rigor. Perera avoids overly complicated problems, instead emphasizing a solid grasp of fundamental principles. The book is well-structured for self-study as well as classroom use, making it an ideal resource for both students and teachers.

For Sri Lankan A Level students pursuing Combined Mathematics, this book—along with its companion volume on Pure Mathematics—is an essential addition to their study resources. Highly recommended.
