Algebra-Bij ganitam

Algebra is a branch of mathematics connected with the study of structure, relation, and quantity.

The origin of Bij-ganitam is ancient India. Persian first learn it from here and then from them the Greeks. The Algebra name is derived from the treatise written by the Persian mathematician Muhammad bin Mūsā al-Khwārizmī  820CE, titled (in Arabic كتاب الجبر والمقابلة )Al-Kitab al-Jabr wa-l-Muqabala (meaning “The Compendious Book on Calculation by Completion and Balancing”)

Major fields of mathematics :

Logic • Set theory • Algebra (Abstract algebra – Linear algebra) • Discrete mathematics • Combinatorics • Number theory • Analysis • Geometry • Topology • Applied mathematics • Probability • Statistics • Mathematical physics • Ring (mathematics) and Field (mathematics)

Elementary and Abstract Algebra

Elementary algebra is the most basic form of algebra. It is taught to students who are presumed to have no knowledge of mathematics beyond the basic principles of arithmetic. Although in arithmetic, only numbers and their arithmetical operations (such as +, −, ×, ÷) occur, in algebra, numbers are often denoted by symbols (such as a, x, y).

Abstract algebra extends the familiar concepts found in elementary algebra and arithmetic of numbers to more general concepts.

The word algebra is also used for various algebraic structures:

Algebra over a field
Algebra over a set
Boolean algebra
F-algebra and F-coalgebra in category theory

Chronology  of key algebraic developments :

Circa 2800 BC: Bodhayan Collected old Theories and compiled in Sulva Sutram [India].  It explained so-called Pythagorean triples algebraically, finds geometric solutions of linear equations and quadratic equations of the forms ax2 = c and ax2 + bx = c, and finds two sets of positive integral solutions to a set of simultaneous Diophantine equations.

Circa 1800 BC: The Old Babylonian Strassburg tablet seeks the solution of a quadratic elliptic equation.
Circa 1600 BC: The Plimpton 322 tablet gives a table of Pythagorean triples in Babylonian Cuneiform script.
Circa 600 BC: Indian mathematician Apastamba, in his Apastamba Sulba Sutra, solves the general linear equation and uses simultaneous Diophantine equations with up to five unknowns.
Circa 300 BC: In Book II of his Elements, Euclid gives a geometric construction with Euclidean tools for the solution of the quadratic equation for positive real roots. The construction is due to the Pythagorean School of geometry.
Circa 300 BC: A geometric construction for the solution of the cubic is sought (doubling the cube problem). It is now well known that the general cubic has no such solution using Euclidean tools.
Circa 100 BC: Algebraic equations are treated in the Chinese mathematics book Jiuzhang suanshu (The Nine Chapters on the Mathematical Art), which contains solutions of linear equations solved using the rule of double false position, geometric solutions of quadratic equations, and the solutions of matrices equivalent to the modern method, to solve systems of simultaneous linear equations.
Circa 100 BC: The Bakhshali Manuscript written in ancient India uses a form of algebraic notation using letters of the alphabet and other signs, and contains cubic and quartic equations, algebraic solutions of linear equations with up to five unknowns, the general algebraic formula for the quadratic equation, and solutions of indeterminate quadratic equations and simultaneous equations.
Circa 150 AD: Hellenized Egyptian mathematician Hero of Alexandria, treats algebraic equations in three volumes of mathematics.
Circa 200: Hellenized Babylonian mathematician Diophantus, who lived in Egypt and is often considered the “father of algebra”, writes his famous Arithmetica, a work featuring solutions of algebraic equations and on the theory of numbers.
