This text investigates the foundational principles of classical number theory while situating these mathematical concepts within their historical development. David G. Burton, an experienced educator, structures the material to serve undergraduate mathematics majors and prospective secondary school teachers. The book relies on a logical progression of theorems and proofs, requiring only a solid foundation in high school algebra to navigate the core concepts effectively.

This text is widely regarded as a standard, accessible introduction for students entering the field of number theory. Its clear, methodical presentation makes it a frequent choice for undergraduate curricula focusing on both theory and historical development.
