Brahmagupta was an Indian mathematician, born in AD in Bhinmal, a state of Rajhastan, India. He spent most of his life in Bhinmal which was under the rule. Brahmagupta was an Ancient Indian astronomer and mathematician who lived from AD to AD. He was born in the city of Bhinmal in Northwest India. Brahmagupta was a famous mathematician and astronomer who lived in seventh century India. His ideas were so profound that they still influence.

The square of a negative or of a positive is positive; [the square] of zero is zero. Both of these texts are actually written in verse. A positive divided by a positive or a negative bikgraphy by a negative is positive; a zero divided by a zero is zero; a positive divided by a negative is negative; a negative divided by a positive is [also] negative.

In his seminal book he provided a formula useful for generating Pythagorean triples and also gave a bigoraphy relation for generating solutions to certain instances of Diophantine equations.

Brahmagupta biography

He is believed to have died sometime after AD. After giving the value of pi, he deals with the geometry of plane figures and solids, such as finding volumes and surface areas or empty spaces dug out of solids.

The details regarding his family life are obscure. The difference between rupaswhen inverted and divided by the difference of the unknowns, is the unknown in the equation.

Brahmagupta was born in AD into an orthodox Shaivite Hindu family.

Imaging two triangles within [a cyclic quadrilateral] with unequal sides, the two diagonals are the two bases.

He explains that since the Moon brahmaguptta closer to the Earth than the Sun, the degree of the illuminated part of the Moon depends on the relative positions of the Sun and the Moon, and this can be computed from the size of the angle between the two bodies.


Some of the work of Bhaskarawhich was published some years later, shows little advancement form that produced by Brahmagupta. Taylor and Francis, pp.

Sometime in the eighth century the work of Brahmagupta was brought to Baghdad where it was translated into Arabic and then subsequently it was translated into Latin, at which point it spread throughout the western world.

He established a formula for the area of cyclic quadrilaterals derived from Heron’s formulaand continued Diophantus’ work by characterizing all the solutions of linear congruences, and by proposing the quadratic Diophantine equation which nowadays is known as Pell equation. He went on to solve systems of simultaneous indeterminate equations stating that the desired variable must first be isolated, and then the equation must be divided by the desired variable’s coefficient.


The key to his solution was the identity, [24]. Not much is known about his early life. Brahmagupta became an astronomer of the Brahmapaksha school, one of the four major schools of Indian astronomy during this period. The work is thought to be a revised version of the received siddhanta of the Brahmapaksha school, incorporated with some of his own new material. When a positive is to be subtracted from a negative or a negative from a positive, then it is to be added.

In chapter eighteen of his BrahmasphutasiddhantaBrahmagupta describes operations on negative numbers.
