Algebra From Wikipedia, the free encyclopedia Jump to: navigation search The English used in this article or section may not be easy for everybody to understand. You can help Wikipedia by making this page or section simpler Algebra is a part of mathematics (math) that deals with techniques for solving equations and inequalities . Some of these techniques require understanding the properties of numbers and math operations used on numbers (adding, subtracting, multiplying or dividing, square roots, raising a number to a power, and taking logarithms). Algebra does this by using letters a b c ,...) or other symbols to represent numbers, either because the numbers are unknown or because the numbers change during the course of the problem, in which case the letters are called variables The purpose of algebra was originally to solve equations, of which linear equations and quadratic equations are examples. The techniques developed to solve such equations often had to do with the properties of the participants in an equation, like how to factor polynomials , or how to solve systems of many equations at once using things like a matrix. The study of

You can use it either as a main text, as a supplement to another text, or for independent study. What's Linear Algebra About? When I started teaching the subject I found three kinds of texts. There were applied mathematics books that avoid proofs and covered the linear algebra only as needed for their applications. There were advanced books that assumed students could understand their elegant proofs and also understand how to answer the homework questions having seen only one or two examples. And, there were books that spent a good part of the semester doing elementary things such as multiplying matrices and computing determinants, only to suddenly change level to working with definitions and proofs. Each of these three types was a problem in my classroom. The applications were interesting but I wanted to focus on the linear algebra. The advanced books were beautiful but my students were not ready for them. And, the level-switching books resulted in a great deal of grief. I took a level-switching book as an undergraduate, so I understood the struggle my students had with this. At the start of the semester they thought that these were like calculus books, where material labelled `proof' should be skipped in favor of the computational examples. Then, when the level switched, no amount of discussion on my part could convince students to switch with it, and the semester ended unhappily.

Math Contests School League Competitions Contest Problem Books Challenging, fun math practice Educational Software Comprehensive Learning Tools Visit the Math League Variables A variable is a symbol that represents a number. Usually we use letters such as n t , or x for variables. For example, we might say that s stands for the side-length of a square. We now treat s s . The area of the square is given by s s . When working with variables, it can be helpful to use a letter that will remind you of what the variable stands for: let n be the n umber of people in a movie theater; let t be the t ime it takes to travel somewhere; let d be the d istance from my house to the park. Expressions An expression is a mathematical term or a sum or difference of mathematical terms that may use numbers, variables, or both. Example: The following are examples of expressions: x y z z Example: Roland weighs 70 kilograms, and Mark weighs k kilograms. Write an expression for their combined weight. The combined weight in kilograms of these two people is the sum of their weights, which is 70 + k Example: A car travels down the freeway at 55 kilometers per hour.

this.name="homeWin"; ancho = screen.width; alto = screen.height; pos_x = (ancho-800)/2; pos_y = (alto-600)/2; These are the lecture notes and tutorial problems for the Linear Algebra module in Mathematics for Informatics 3 (MAT-2-mi3/am3i) . They are a revised version of the ones used in the 2004-2005 session, which were themselves revised due to changes in the syllabus from the ones used in the 2003-2004 session. The original lecture notes have benefited from extant notes on linear algebra by John Meldrum and on polynomials by Andrew Ranicki Linear algebra is the study of vector spaces and linear maps. The module is divided into three parts. During the first part, which will take up about half of the semester, we will study real vector spaces and their linear maps. We will discuss subspaces, linear (in)dependence, bases, dimension, linear maps and linear transformations and their relation to matrices, the effect of changing basis, eigenvalues and eigenvectors and diagonalisation. The second part will be devoted to univariate polynomials. The third and final part will serve as an introduction to algebraic coding theory, concentrating for definiteness on binary linear codes.

Algebra Classical intermediate algebra is the toolbox of mathematical analysis Contents Introduction Expressions and Polynomials Identity Transformations Partial Fractions and Root Transformations ... References Introduction Arithmetic, although very useful and the foundation of mathematics, is not suited to making general statements about numbers, nor to reasoning about their abstract properties. Geometry, however, powerfully extends arithmetic to these areas. A geometric figure, for example a triangle, does not refer to any specific triangle, but to any triangle satisfying the conditions of the problem. Conclusions drawn on the basis of these diagrams refer to all examples. Another way to extend arithmetic is to introduce symbols that stand for any number, just as a triangle in geometry stands for any triangle. This step appears to have been taken by Diophantus in the 3rd century, and re-introduced to Europe via the Arabs about a thousand years later together with algorism, which is arithmetic using written symbols, the Hindu-Arabic digits. This reasoning was called by the Italian word algebra , derived from the Arabic al-jabr , a "putting together." Its operations were very suited to calculations on paper, and it developed rapidly in the 16th and 17th centuries, applied at first mainly to the solution of equations.
