Mahavira was a 14th-century Indian mathematician who wrote the Ganita-Sara-Sangraha.

The Ganita-Sara-Sangraha was written in Sanskrit, which was the lingua franca of Indian scholarship in the 14th century.

The Ganita-Sara-Sangraha is a comprehensive work that covers a wide range of mathematical topics, including arithmetic, algebra, geometry, and trigonometry.

The Ganita-Sara-Sangraha contains the first known proof of the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Mahavira used the completing the square method to solve quadratic equations. This method involves adding and subtracting a constant term to the equation in order to make it a perfect square.

Mahavira used the Cardano method to solve cubic equations. This method involves a series of algebraic transformations that reduce the cubic equation to a quadratic equation, which can then be solved using the quadratic formula.

Mahavira used the Ferrari method to solve quartic equations. This method involves a series of algebraic transformations that reduce the quartic equation to a cubic equation, which can then be solved using the Cardano method.

Mahavira did not develop a method for solving quintic equations. The Abel-Ruffini theorem, which was proved in the 19th century, states that there is no general algebraic method for solving quintic equations.

Mahavira used the substitution method to solve simultaneous equations. This method involves substituting one equation into another in order to eliminate one variable.

Mahavira used the Diophantine analysis to solve indeterminate equations. This method involves finding integer solutions to equations that have an infinite number of solutions.

Mahavira used the factorial method to solve problems involving permutations and combinations. This method involves multiplying the numbers from 1 to the number of objects being arranged.

Mahavira used the arithmetic progression to solve problems involving progressions. This method involves finding the sum of a series of numbers that increase or decrease by a constant amount.

Mahavira used the simple interest formula to solve problems involving interest. This formula involves multiplying the principal amount by the interest rate and the time period.

Mahavira used the rule of mixtures to solve problems involving mixtures. This method involves finding the average value of a mixture of two or more substances.

Mahavira used the tangent ratio to solve problems involving shadows. This method involves finding the ratio of the length of a shadow to the length of the object casting the shadow.
