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 ...

Algebra, branch of mathematics in which arithmetical operations and formal manipulations are applied to abstract symbols rather than specific numbers. This article presents algebra’s history, tracing the evolution of the equation, number systems, symbols, and the modern abstract structural view of algebra.
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 ...
