Aryabhata is considered the Father of Indian Mathematics due to his significant contributions to the field. He is known for his work on arithmetic, algebra, trigonometry, and astronomy.

The Pythagorean Theorem is a well-known theorem in geometry that relates the sides of a right triangle. It states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

Brahmagupta is credited with developing the concept of zero and its use in mathematical operations. He also formulated rules for working with negative numbers and introduced the decimal system.

Bhaskara's Theorem, also known as the Heron's Formula, provides a method for calculating the area of a triangle given the lengths of its sides.

Brahmagupta is known for his work on indeterminate equations, which are equations with multiple unknown variables. He developed methods for solving these equations and provided solutions to specific problems.

The Euclidean Theorem, also known as the Angle Sum Theorem, states that the sum of the interior angles of a triangle is always equal to 180 degrees.

Bhaskara is known for his work on Diophantine equations, which are equations with integer coefficients and integer solutions. He developed methods for solving these equations and provided solutions to specific problems.

Bhaskara's Theorem states that the product of two consecutive integers is always odd. This theorem can be used to prove various properties of numbers and integers.

Bhaskara is known for his work on permutations and combinations, which are mathematical techniques for counting the number of possible arrangements or selections from a given set of elements.

Brahmagupta's Theorem provides a formula for calculating the area of a circle given its radius. It states that the area of a circle is equal to pi multiplied by the square of its radius.

Varahamihira is known for his work on magic squares, which are square grids filled with numbers such that the sum of the numbers in each row, column, and diagonal is the same.

Bhaskara's Theorem provides a formula for calculating the sum of the squares of the first n natural numbers. It states that the sum is equal to n(n+1)(2n+1)/6.

Bhaskara is known for his work on the Fibonacci sequence, which is a series of numbers where each number is the sum of the two preceding ones. He studied the properties of the Fibonacci sequence and provided solutions to problems related to it.

Brahmagupta's Theorem provides a formula for calculating the sum of the cubes of the first n natural numbers. It states that the sum is equal to the square of the sum of the first n natural numbers.

Bhaskara is known for his work on the binomial theorem, which is a formula for expanding the power of a binomial expression. He provided a general formula for the binomial theorem and used it to solve various problems.
