The dates of Greek mathematics are more certain than the dates of earlier mathematical writing, since a large number of chronologies exist that, overlapping, record events year by year up to the present day. Even so, many dates are uncertain; but the doubt is a matter of decades rather than centuries. Greek mathematics is characterized by its originality, its depth, its abstraction, and its reliance on logic. The Greeks were the first to discover irrational numbers (due to the Pythagoreans), Eudoxus's method of exhaustion, and the Sie ...

The earliest known mathematics in ancient India dates back to 3000 BC with the Indus Valley civilization. After its collapse in 1700 BC however, writing was absent in South Asia for a long period. There is considerable controversy regarding the dates when writing was re-developed in India and when the Brahmi script was developed.[5] Some scholars, such as Georg Bühler, date the Brahmi script as early as the 8th century BC, others from the Maurya dynasty in the 4th century BC. Some evidence dates it to 600 BC (see Brāhmī), while some schol ...

Mathematics is often defined as the study of topics such as quantity, structure, space, and change. Another view, held by many mathematicians, is that mathematics is the body of knowledge justified by deductive reasoning, starting from axioms and definitions. Practical mathematics, in nearly every society, is used for such purposes as accounting, measuring land, or predicting astronomical events. Mathematical discovery or research often involves discovering and cataloging patterns, without regard for application. Today, the natural sciences, engineering, economics, and medici ...
