Forms: also with capital initials.

Origin: Formed within English, by compounding. Etymons: number n., theory n.

Etymology: < number n. + theory n. In sense 2 after French théorie des nombres (A. M. Legendre Essai sur la théorie des nombres (1798)). Compare German Zahlentheorie (1863 or earlier).

1. A doctrine or theory concerned with the cosmic significance of numbers and proportions, esp. that derived from the ancient Pythagorean school. historical.

2. Mathematics. The branch of mathematics dealing with the properties and relationships of numbers, esp. the positive integers. Cf. theory n. 1b.
