Brahmagupta's work, particularly his treatise Brahmasphutasiddhanta, had a profound impact on Islamic mathematicians. His ideas on arithmetic, algebra, and astronomy were widely studied and adopted in the Islamic world.

Arithmetic progression is an Indian mathematical concept that involves finding the sum of a series of numbers in which each term is obtained by adding a constant to the previous term. It is also known as linear progression.

Completing the square is an Indian mathematical concept that was used by Islamic mathematicians to solve quadratic equations. It involves adding and subtracting a constant term to the equation in order to make it a perfect square.

Brahmagupta's formula is an Indian mathematical concept that involves finding the area of a triangle using half the product of its base and height. It is also known as Heron's formula.

Trigonometric ratios are an Indian mathematical concept that was used by Islamic mathematicians to develop the concept of sine and cosine. These ratios involve the relationship between the sides of a right triangle.

Gauss's formula is an Indian mathematical concept that involves finding the sum of the first n natural numbers. It is also known as the arithmetic series formula.

Madhava's series is an Indian mathematical concept that was used by Islamic mathematicians to develop the concept of logarithms. It is an infinite series that can be used to approximate the value of the natural logarithm of a number.

Bhaskara's formula is an Indian mathematical concept that involves finding the area of a circle using pi multiplied by the square of its radius. It is also known as the circle area formula.

Madhava's series is an Indian mathematical concept that was used by Islamic mathematicians to develop the concept of calculus. It is an infinite series that can be used to approximate the value of the derivative and integral of a function.

Bhaskara's formula is an Indian mathematical concept that involves finding the volume of a sphere using four-thirds pi multiplied by the cube of its radius. It is also known as the sphere volume formula.
