Brahmagupta was born in Ujjain, which is located in the modern-day state of Madhya Pradesh, India.

Brahmagupta's treatise on mathematics and astronomy was called the Brahmasphutasiddhanta.

The Brahmasphutasiddhanta is divided into four parts: the first part deals with arithmetic, the second part deals with algebra, the third part deals with astronomy, and the fourth part deals with astrology.

Brahmagupta's formula for finding the area of a triangle is $A = \frac{1}{2}bh$, where $b$ is the base of the triangle and $h$ is the height of the triangle.

Brahmagupta's formula for finding the volume of a sphere is $V = \frac{4}{3}\pi r^3$, where $r$ is the radius of the sphere.

Brahmagupta's theorem states that the sum of the squares of the diagonals of a cyclic quadrilateral is equal to the sum of the squares of the sides.

Brahmagupta was the first mathematician to develop a general method for solving quadratic equations.

Brahmagupta's method for solving quadratic equations is known as Brahmagupta's formula.

Brahmagupta's formula for solving quadratic equations is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Brahmagupta also made significant contributions to the field of astronomy.

Brahmagupta's astronomical work, the Brahmasphutasiddhanta, contains a table of sines.

Brahmagupta's table of sines is the first known table of sines to be calculated using a scientific method.

Brahmagupta's work was influential in the development of mathematics and astronomy in India and beyond.

Brahmagupta is considered to be one of the greatest mathematicians and astronomers of his time.

Brahmagupta's work is still studied and admired by mathematicians and astronomers today.
