Mathematics is a discipline which includes the study of various topics such as quantity, space, change and structure. It is classified into two primary areas- pure mathematics and applied mathematics. Pure mathematics studies only the concepts of mathematics. It does not delve into any applications of such concepts. Applied mathematics focuses on the use of mathematical concepts in diverse fields such as computer science, engineering and business. Some of the important areas of mathematics are algebra, number theory, geometry, mathematical analysis, arithmetic, etc. It plays an important role in many fields such as natural science, engineering, social sciences, medicine and finance. Advancements in applied mathematics resulted in the development of new mathematical disciplines such as statistics and game theory. This textbook elucidates the fundamental concepts of mathematics. It presents this complex subject in the most comprehensible and easy to understand language. This book will serve as a valuable source of reference for those interested in mathematics.
