The word, Algebra is an Arabic word meaning bringing together broken parts . This useful tool of mathematics was invented by the 9th century Arab mathematician, Mohammed Ibn Musa Al-Khwarizmi (from whos Europeanised name comes the word, algorithm Algebra allows the finding of unknown numbers from information given. Here are two examples of the type of problems that can be solved using algebra. Example 1: When six is added to this number, it gives nine. What is the number? Example 2: A number is multiplied by itself. Three times that same number is subtracted. Finally, two is added. The total is now zero. What is the number? Example 1 is trivial. The number has to be three. Example 2 is much harder to guess. I will return to it later. Rules And Notation In algebra, letters are used in place of numbers that are not known. These letters are then manipulated in accordance with certain rules until an answer appears. The usual letter for the unknown number is

27. Algebra -- From Wolfram MathWorld The word algebra is a distortion of the Arabic title of a treatise by alKhwarizmi about algebraic methods. In modern usage, algebra has several meanings. http://mathworld.wolfram.com/Algebra.html

Search Site Algebra Applied Mathematics Calculus and Analysis ... Renze Algebra The word "algebra" is a distortion of the Arabic title of a treatise by al-Khwarizmi about algebraic methods. In modern usage, algebra has several meanings. One use of the word "algebra" is the abstract study of number systems and operations within them, including such advanced topics as groups rings invariant theory, and cohomology . This is the meaning mathematicians associate with the word "algebra." When there is the possibility of confusion, this field of mathematics is often referred to as abstract algebra The word "algebra" can also refer to the "school algebra" generally taught in American middle and high schools. This includes the solution of polynomial equations in one or more variables, and basic properties of functions and graphs . Mathematicians call this subject " arithmetic ," reserving the word "algebra" for the more advanced aspects of the subject. Finally, the word is used in a third way, not as a subject area but as a particular type of algebraic structure. Formally, an algebra is a

Welcome! Login Subject Math > Algebra Algebra Algebra, abstract when you face it after having fun with a lot of arithmetic, is a challenge when encountered at first. Let the Algebra guru’s at TutorVista make you feel at home with variables which come in different types, dependent, independent and what not! Learn basics of algebra starting from properties of addition and multiplication, reducing fractions to various identities, plotting graphs postulates, finding roots of polynomials, linear equation solving to advanced topics like relations, functions, composite-functions, and inequalities. Algebra has huge applications in real life problems and also in solving problems in Physics, Chemistry, Statistics and a lot more. Expansions In algebra we come across certain products very frequently. For e.g., (a + b) , (a + b) (a + b + c) etc. These are nothing but products of binomials or trinomials. We derive the formulae for these products and apply them whenever necessary. These expansions help us to avoid elaborate multiplications and make calculations quicker. Framing of Formulae A formula is formed by using: (a) mathematical symbols and variables (b) given conditions, and (c) simplification.
