Chinese mathematics made early contributions, including a place value system and the first use of negative numbers. [ 6 ] [ 7 ] The Hindu–Arabic numeral system and the rules for the use of its operations, in use throughout the world today evolved over the course of the first millennium AD in India and were transmitted to the Western world via ...
He was "the first who introduced the theory of algebraic calculus". [12] c. 1000 – Abu Mansur al-Baghdadi studied a slight variant of Thābit ibn Qurra's theorem on amicable numbers, and he also made improvements on the decimal system. 1020 – Abu al-Wafa' al-Buzjani gave the formula: sin (α + β) = sin α cos β + sin β cos α.

He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos ( c. 582 – c. 507 BC ) established the Pythagorean school , whose doctrine it was that mathematics ruled the universe and whose motto was "All is ...
Euclid (fl. 300 BC) is often referred to as the "founder of geometry" [5] or the "father of geometry" because of his incredibly influential treatise called the Elements, which was the first, or at least one of the first, axiomatized deductive systems.

The Egyptian mathematician Abū Kāmil Shujā ibn Aslam (c. 850–930) was the first to accept irrational numbers in the form of a square root or fourth root as solutions to quadratic equations or as coefficients in an equation. [76] He was also the first to solve three non-linear simultaneous equations with three unknown variables. [77]
The first genre, with A = 1, is the octave itself (or its duplicates); the second genre, 2 m.3, is the octave divided by the fifth (fifth + fourth, C–G–C); the third genre is 2 m.5, major third + minor sixth (C–E–C); the fourth is 2 m.3 2, two-fourths and a tone (C–F–B ♭ –C); the fifth is 2 m.3.5 (C–E–G–B–C); etc. Genres ...
