Brahmagupta was an Indian mathematician and astronomer who lived in the 6th century CE. He is best known for his work on the quadratic equation, which he solved using a method that is still used today.

The Pythagorean theorem is a fundamental theorem of geometry that states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. It is named after the Greek mathematician Pythagoras, who is believed to have first discovered it.

Aryabhata was an Indian mathematician and astronomer who lived in the 5th century CE. He is best known for his work on the decimal system, which he used to develop a system of arithmetic that was much more efficient than the traditional methods used at the time.

Bhaskara II was an Indian mathematician and astronomer who lived in the 12th century CE. He is best known for his work on the Fibonacci sequence, which is a series of numbers in which each number is the sum of the two preceding numbers. The Fibonacci sequence has many applications in mathematics and computer science.

He is best known for his work on the decimal system, which he used to develop a system of arithmetic that was much more efficient than the traditional methods used at the time. Aryabhata also developed the concept of the irrational number, which is a number that cannot be expressed as a fraction of two integers.

Srinivasa Ramanujan was an Indian mathematician who lived in the 20th century CE. He is best known for his work on the transcendental number, which is a number that cannot be expressed as a root of any polynomial with rational coefficients. Ramanujan also developed many other important mathematical theorems and formulas.
