Basic Number Theory by S. B. Malik is a widely acclaimed, student-friendly textbook designed to provide a comprehensive, step-by-step introduction to fundamental concepts in integer arithmetic, modular structures, and classical number theory. Published by Vikas Publishing House, the book is praised for its clear presentation, accessible proofs, and numerous illustrative examples. 

This textbook is extensively prescribed across BS Mathematics, BS Physics, Computer Science, and competitive examination preparation courses (such as CSS and PMS) at leading Pakistani universities and colleges. 

The book thoroughly covers the complete spectrum of elementary number theory without using bullet points. It begins with divisibility theory and the Division Algorithm, detailing greatest common divisors, least common multiples, Euclidean Algorithm, and linear Diophantine equations. It then explores prime numbers and their properties, including the Fundamental Theorem of Arithmetic and prime distribution.
