Who is Brahmagupta?

He was born in Bhinmal, Northwest India.

In addition to solving equations, Brahmagupta studied mathematical systems, including systems of simultaneous equations.

In addition to astronomy, Brahmagupta also wrote extensively about mathematical logic.

Brahmagupta's mathematical methods led to the discovery of the Earth's distance from the Sun.

He also discovered the formula for calculating the area of a four-sided figure.

He also developed an accurate method to calculate the length of a year and mentioned the importance of gravity, a property of all bodies falling toward the earth.

His work in mathematics was extensive and he was particularly noted for his contributions to geometry.

He wrote a famous formula for the area of a cyclic quadrilateral.

His work was also notable in astronomy, as he formulated equations to determine the celestial movements.
