Linear Equations
Aryabhata was the Indian mathematician who described the solution to the indeterminate linear equation in his treatise called Aryabhatiya. It obtains whole-number solutions to linear equations by a method equivalent to the modern one. -

Cubic Equation
In the early 13th century, the great Italian mathematician Leonardo Fibonacci achieved a close approximation to the solution of the cubic equation. -
Symbolic Notation
Francois Viete developed the improved symbolic notation for various powers of an unknown. -
General Cubic Equation
Early in the 16th century, the Italian mathematicians Scipione del Ferro, Niccolò Tartaglia, and Gerolamo Cardano solved the general cubic equation in terms of the constants appearing in the equation. -
Introduction of Symbols for the Unknown
As a result of this development, Book III of La géometrie(1637), written by the French philosopher and mathematician René Descartes, looked much like a modern algebra text.
