what is the history of algebra?

Answer 1

"Algebra" is an Arab word. They were the first to make a systematic study of it before the European medieval period. However, forerunners of algebra involving finding unknowns began as early as the ancient Babylonians.

Answer 2

The origins of algebra can be traced to the ancient Babylonians,[1] who developed an advanced arithmetical system with which they were able to do calculations in an algebraic fashion. With the use of this system they were able to apply formulas and calculate solutions for unknown values for a class of problems typically solved today by using linear equations, quadratic equations, and indeterminate linear equations. By contrast, most Egyptians of this era, and most Indian, Greek and Chinese mathematicians in the first millennium BC, usually solved such equations by geometric methods, such as those described in the Rhind Mathematical Papyrus, Sulba Sutras, Euclid's Elements, and The Nine Chapters on the Mathematical Art. The geometric work of the Greeks, typified in the Elements, provided the framework for generalizing formulae beyond the solution of particular problems into more general systems of stating and solving equations.

The word "algebra" is named after the Arabic word "al-jabr" from the title of the book al-Kitāb al-muḫtaṣar fī ḥisāb al-ğabr wa-l-muqābala, meaning The book of Summary Concerning Calculating by Transposition and Reduction, a book written by the Persian Muslim mathematician Muhammad ibn Mūsā al-khwārizmī in 820. The word Al-Jabr means "reunion". The Hellenistic mathematician Diophantus has traditionally been known as "the father of algebra" but debate now exists as to whether or not Al-Khwarizmi should take that title from Diophantus.[2] Those who support Al-Khwarizmi point to the fact that much of his work on reduction is still in use today and that he gave an exhaustive explanation of solving quadratic equations. While those who support Diophantus point to the fact that the algebra found in Al-Jabr is more elementary than the algebra found in Arithmetica and that Arithmetica is syncopated while Al-Jabr is fully rhetorical.[3] Another Persian mathematician Omar Khayyam developed algebraic geometry and found the general geometric solution of the cubic equation. The Indian mathematicians Mahavira and Bhaskara, and the Chinese mathematician Zhu Shijie, solved various cubic, quartic, quintic and higher-order polynomial equations.

Another key event in the further development of algebra was the general algebraic solution of the cubic and quartic equations, developed in the mid-16th century. The idea of a determinant was developed by Japanese mathematician Kowa Seki in the 17th century, followed by Gottfried Leibniz ten years later, for the purpose of solving systems of simultaneous linear equations using matrices. Gabriel Cramer also did some work on matrices and determinants in the 18th century. Abstract algebra was developed in the 19th century, initially focusing on what is now called Galois theory, and on constructibility issues.

The History of Algebra
Algebra provides a generalization of arithmetic by using symbols, usually letters, to represent numbers. For example, it is obviously true that
2 + 3 = 3 + 2
This arithmetic statement can be generalized using algebra to
x + y = y + x
where x and y can be any number. Algebra has been studied for many centuries. Babylonian, and ancient Chinese and Egyptian mathematicians proposed and solved problems in words, that is, using "rhetorical algebra". However, it was not until the 3rd century that algebraic problems began to be considered in a form similar to those studied today.
In the 3rd century, the Greek mathematician Diophantus of Alexandria wrote his book Arithmetica. Of the 13 parts originally written, only six still survive, but they provide the earliest record of an attempt to use symbols to represent unknown quantities. Diophantus did not consider general methods in Arithmetica, but instead solved a large number of practical problems.
Several Indian mathematicians carried out important work in the field of algebra in the 6th and 7th centuries. These include Aryabhatta, whose book entitled Aryabhatta included work on linear and quadratic equations, and Brahmagupta, who presented a general solution for a quadratic equation.
The next major development in the history of algebra was the book al-Kitab al-muhtasar fi hisab al-jabr wa'l-muqabala ("Compendium on calculation by completion and balancing"), written by the Arabic mathematician Al-Khwarizmi in the 9th century. The word algebra is derived from al-jabr, or "completion". This book developed methods for solving six different types of quadratic equations, and contained the first systematic consideration of the subject separately from number theory.
In about 1100, the Persian mathematician Omar Khayyam wrote a treatise on algebra based on Euclid's methods. In it he identified 25 types of equations and made the first formal distinction between arithmetic and algebra. Some time later during the 12th century, Al-Khwarizmi's works were translated and became available to Western scholars. In the 13th century Leonardo Fibonacci wrote some important and influential books on algebra. Other highly influential works were those of the Italian mathematician Luca Pacioli (1445-1517), and of the English mathematician Robert Recorde (1510-1558).
Rules for solving cubic equations were discovered about 1515 by Scipione del Ferro (c. 1465-1526), and for the quartic equation by Ludovico Ferrari (1522-1565) about 1545. In 1824 Niels Henrik Abel (1802-1829) finally proved that, in general, it is not possible to give general rules of this kind for solving equations of the fifth degree or higher.
Further contributions to the symbols used in algebra were made in the late 16th century and the 17th century by François Viète (1540-1603) and René Descartes, among others.
Complex and negative roots were a later discovery, and took some time to become accepted. In 1799, Karl Friedrich Gauss proved the fundamental theorem of algebra, which had been proposed as early as 1629.
In the 19th and 20th centuries algebra has become much more abstract and has grown to include much more than the theory of equations. Modern developments in algebra include group theory and the study of matrices.


Boolean Algebra
Boolean algebra is the algebra of sets and of logic. It uses symbols to represent logical statements instead of words. Boolean algebra was formulated by the English mathematician George Boole in 1847. Logic had previously been largely the province of philosophers, but in his book, The Mathematical Analysis of Logic, Boole reduced the whole of classical, Aristotelian logic to a set of algebraic equations. Boole's original notation is no longer used, and modern Boolean algebra now uses the symbols of either set theory, or propositional calculus.
Boolean algebra is an uninterpreted system - it consists of rules for manipulating symbols, but does not specify how the symbols should be interpreted. The symbols can be taken to represent sets and their relationships, in which case we obtain a Boolean algebra of sets. Alternatively, the symbols can be interpreted in terms of logical propositions, or statements, their connectives, and their truth values. This means that Boolean algebra has exactly the same structure as propositional calculus.

Boolean Algebra and Computing
The most important application of Boolean algebra is in digital computing. Computer chips are made up of transistors arranged in logic gates. Each gate performs a simple logical operation. For example, an AND gate produces a high voltage electrical pulse at the output r if and only if a high voltage pulse is received at both inputs p, q. The computer processes the logical propositions in its program by processing electrical pulses - in the case of the AND gate, the proposition represented is p Ù q º r. A high pulse is equivalent to a truth value of "true" or binary digit 1, while a low pulse is equivalent to a truth value of "false", or binary digit 0.
The design of a particular circuit or microchip is based on a set of logical statements. These statements can be translated into the symbols of Boolean algebra. The algebraic statements can then be simplified according to the rules of the algebra, and translated into a simpler circuit design.

Algebraic Equations
An algebraic equation shows the relationship between two or more variables. The equation below states that the area (a) of a circle equals p (pi, a constant) multiplied by the radius squared (r 2). Given a particular value for a or r, the equation can be solved (a value can be found) for the other variable. Given another equation that is simultaneously true, for example c = 2pr, we can substitute c/2p for r into the first equation. This gives a new equation, a = c 2/4p.

Algebraic Operations
An operation is any procedure carried out on one or more original values (the operands) to generate a new value. The idea of an operation is fundamental to mathematics. For example, addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication, and division. The operation of addition, when carried out on the operands 3 and 4, generates a sum of 7. Even quite simple algebraic techniques, such as factorization, depend on a thorough understanding of basic operations. There is always a well-defined rule for calculating the result of a particular operation.
For many operations, the result is one value, regardless of the number of input values. (One exception is the operation of taking square roots - these may be positive or negative). Such operations may be described as one-to-one or many-to-one mappings, or functions.


An Algebra of Operators
The symbol used to indicate an operation is called an operator. For example, the operator for addition is the plus sign (+), and the operator for integration is the integral sign. In some cases, different symbols are used to represent the same operator. In computing, the operator * is used to mean exactly what the operator ×, "times", means in arithmetic. Different operators are used in different areas of mathematics. For example, in logic, there are several sets of operators that are used to express logical relationships.
The manipulation of operators together with other mathematical symbols constitutes an algebra of operations. Discovering rules in such an algebra helps to simplify calculations. To give an elementary example, the expression -(-(-3)) can be simplified to -3. Mathematicians working in the more abstract reaches of algebra investigate general properties of operations. For example, group theory is concerned with sets that are closed under associative operations - that is, sets that contain the results of the operation when carried out on the original elements.
