Indian mathematics

The now well-known contribution of the Indian mathematics to mathematics was the invention of zero. The zero- arrived on the territories occupied by the Arabs space under successive placement of the Persian al - Khwarizmi and the Italian Leonardo Fibonacci to Europe. Thus the basis was laid that the Indian decimal system could replace the Roman numeral system.

Already 499 AD was given by the Indian mathematician Aryabhata a remarkably accurate value of Pi: 62832/20.000 = 3.1416, but the value is not set by itself. Brahmagupta claimed 640, the value is equal to the square root of ten, approximately 3.1622. Even later was often expected 22/7, whether out of ignorance or a more accurate value for the simplification is unclear. Madhava has stated in the 14th century in his work Karanapaddhati the value of 3.14159265359 using the later " expansion according to Gregory " or Leibniz series mentioned method.
