Sthananga Sutra
Jain the mathematician writes the “Sthananga Sutra”. This contains to work of the theory of numbers, arithmetical operations, geometry, operations with fractions, simple equations, cubic equations, quartic equations, and permutations and combinations. -

Treating algebra
Hero of Alexandria starts to think about algebraic equations. She treats them in three volumes of mathematics. Also he found a method of square roots. -

Father of algebra
Hellenistic mathematician Diophantus is the father of algebra. He writes the Arithmetica. That is a work that has solutions of algebraic equations. -

Solving indeterminate solutions
Brahmagupta invents solving indeterminate solutions. He uses now letters from the alphabet to apply to the equations. Which was in the 2nd degree. -

Second degree
Abū Sahl al-Qūhī starts to solve in the second degree of math. His equations passed the 1st degree because they were very intelligent. He worked with shapes and proved that he can switch up shapes to be a whole new one. -

Definition of algebra
Al-Samawal gives a definition of algebra. He starts to operate unknown numbers. He follows after arithmetician on the known. -

Liber Abaci
Leonardo Fibonacci makes “Liber Abaci”. It is his work on algebra that he published to help people learn. He introduced Arabic numerals to Europe. -
Complex numbers
Caspar Wessel vectors with complex numbers. He also studies complex numbers in geometrical equations. -
School
Algebra is finally introduced in schools. Harvard and other colleges required admission of algebra. It eventually took a big role in mathematics in every other school.
