Algebra is a branch of mathematics that deals with abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication. Elementary algebra is the main form of algebra taught in schools ...

Here is a set of notes used by Paul Dawkins to teach his Algebra course at Lamar University. Included area a review of exponents, radicals, polynomials as well as indepth discussions of solving equations (linear, quadratic, absolute value, exponential, logarithm) and inqualities (polynomial, rational, absolute value), functions (definition, notation, evaluation, inverse functions) graphing ...
Algebra is the branch of mathematics that deals with symbols (or variables) and the rules for manipulating them. It is mainly divided into two types: Elementary Algebra (Taught in Schools): Deals with variables and operations like addition, subtraction, multiplication, and powers. Example, x + 10 = 100, x2 - 2x + 1 = 5, and x + y = 20. Abstract Algebra (Taught in Colleges): Deals with groups ...
