Brahmagupta(598 AD – 668 AD) was an Indian mathematician and also a astronomer.

Zero and its operation are first defined by Brahmagupta in AD 628.

Brahmagupta was the first to give rules to compute with zero.

Brahmagupta's most famous result in geometry is his formula for cyclic quadrilaterals. Given the lengths of the sides of any cyclic quadrilateral, Brahmagupta gave an approximate and an exact formula for the figure's area,
