    Study Notes

    Key Algebra Concepts

    • Variable: Represents a quantity that can change or vary in mathematical expressions.
    • PEMDAS: Acronym that stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It is a guideline for the order of operations in algebra.
    • Polynomial Form: The representation of a polynomial as a sum of terms; each term consists of a coefficient and a variable raised to a whole number exponent.
    • Coefficient: In algebraic notation, it denotes the numerical factor multiplied by a variable within a term.

    Polynomial and Its Structure

    • Polynomial: A mathematical expression that is written as a sum of terms, where each term is comprised of a coefficient and variables raised to powers.
    • Expanded Form: Refers to the expression of a polynomial by detailing all its terms; showing each component clearly instead of as a product or factorized form.

    Importance of PEMDAS

    • Purpose of PEMDAS: Ensures clarity and accuracy in calculations by instructing the order in which different operations should be performed. It helps avoid confusion in complex mathematical expressions.
