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." And we'll take that as a theme throughout the whole (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.
