## About Number Nine Colouring Page

The earliest use of the irregular numbers is found in the Sulba Sutra of India composed of about 800-500 BC. Evidence of the earliest known non-racial numbers derived from Pythagoras, or more specifically his follower Hippasus of Metapontum, which produced the most probable geometric evidence of square root from 2. According to the story, Hippasus discovered the irrelevant number when attempting to portray the cause of power two 2 as a fraction. However, Pythagoras believes in absolute numbers, and can not accept the existence of non-rational numbers. He was unable to prove his absence through logic, but his beliefs were incapable of accepting the existence of a non-racial number then he sentenced Hippasus to death by abolishing it.

The 16th century saw the ultimate acceptance of negative numbers, integers and fractions by Europeans. The 17th century saw a decimal fraction with modern notation widely used by mathematicians. However, only during the 19th century was the ratio of the non-ratio to algebra and transcendental, and a scientific study of the theory of monospatial irreversibility arose after a long period of time since Euclid’s time. 1872 witnessed the publication of the theories of Karl Weierstrass (by his son Kossak), Heine (Crelle, 74), Georg Cantor (Annalen, 5), and Richard Dedekind. In 1869 Méray’s study deviated from a similar point to Heine, but the theory was generally referred to in 1872. Keadah Weierstrass was put forward entirely by Pincherle (1880), and Dedekind’s cousin received more prominence through the author’s continued work (1888 ) and followed by support by Paul Tannery (1894). Weierstrass, Cantor, and Heine founded their own theories in infinite series, while Dedekind founded his theory on the idea of ​​deduction (Schnitt) in a real number system, separating all the ratios into two groups that viewed certain common features. The subject then received further contributions in the hands of Weierstrass, Kronecker (Crelle, 101), and Méray.

The fractional breakdown closely related to the non-ratio number (and by Cataldi, 1613), attracted attention in the hands of Euler, and in the early 19th century was highlighted by Joseph Louis Lagrange’s writing. Other important contributions were also made by Druckenmüller (1837), Kunze (1857), Lemke (1870), and Günther (1872). Ramus (1855) first linked this subject with determinant, sparking further contributions by Heine, Möbius, and Günther, in the Kettenbruchdeterminanten theory. Dirichlet also adds to the general theory, as much as contributors to this subject application.
