Contant, Variable and Algebraic Expressions
This document provides information about exponents, coefficients, variables, constants, terms, and evaluating algebraic expressions. It defines exponents as numbers multiplied by themselves. Numerical coefficients are constant factors in monomials, while literal coefficients are variable factors. Variables can take different values, while constants have fixed values. Terms are made up of constants and variables separated by + and - symbols. Terms are classified as monomials, binomials, trinomials, or multinomials. Algebraic expressions can be evaluated by following steps that substitute values for variables.
