Overview

Algebra extends arithmetic by using literal numbers such as x, y, z, a, b, and c to represent numbers. It is more precise, more general, and easier for solving problems than arithmetic. An algebraic expression is a combination of numbers, variables, and arithmetical operations. A polynomial is a spe

Key Concepts

A variable is a literal number

A variable is a literal number which can have different values. For example, x can represent a month and can take 12 different values.

A constant is a literal number

A constant is a literal number which has a fixed value. For example, a can represent the year 2009 and remain fixed.

A combination of numbers

A combination of numbers, variables, and arithmetical operations. Terms in an expression are separated by + or - signs.

A polynomial is an algebraic expression

A polynomial is an algebraic expression in which variables do not occur in the denominator, exponents of variables are whole numbers, and numerical co

A monomial has one term

A monomial has one term, a binomial has two terms, and a trinomial has three terms.
