Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure mathematics devoted primarily to the study of the integers and integer-valued functions.German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." Most if not all universities worldwide offer introductory courses in number theory for math majors and in many cases as an elective course. (IMO ShortList 1998, Number Theory Problem 5) Determine all positive integers n for which there exists an integer m such that 2n − 1 is a divisor of m2 + 9. 6. It is the study of the set of positive whole numbers which are usually called the set of natural numbers. And we'll take that as a theme throughout the whole Modern number theory is a broad subject that is classified into subheadings such as elementary number theory, algebraic number theory, analytic number theory, and geometric number theory. .
