What mathematical topic did Brahmagupta not work on?

His rules for arithmetic on negative numbers and zero are quite close to the modern understanding, except that in modern mathematics division by zero is left undefined.

How did Brahmagupta discover negative numbers?

In India , negative numbers did not appear until about 620 CE in the work of Brahmagupta (598 – 670) who used the ideas of ‘fortunes’ and ‘debts’ for positive and negative. By this time a system based on place-value was established in India, with zero being used in the Indian number sytem.

What was Brahmagupta known for?

Brahmagupta was an Ancient Indian astronomer and mathematician who lived from 597 AD to 668 AD. He was born in the city of Bhinmal in Northwest India. Although Brahmagupta thought of himself as an astronomer who did some mathematics, he is now mainly remembered for his contributions to mathematics.

Did Brahmagupta invented zero?

History of Math and Zero in India The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628.

What kind of person was Harish Chandra Roy?

Harish-Chandra FRS (11 October 1923 – 16 October 1983) was an Indian American mathematician and physicist who did fundamental work in representation theory, especially harmonic analysis on semisimple Lie groups.

What is the theory of Brahmagupta?

In geometry, Brahmagupta’s theorem states that if a cyclic quadrilateral is orthodiagonal (that is, has perpendicular diagonals), then the perpendicular to a side from the point of intersection of the diagonals always bisects the opposite side. It is named after the Indian mathematician Brahmagupta (598-668).

Was zero invented or discovered?

The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.
