      Important Algebra Terms
    • Variable: A symbol (usually a letter like x or y) representing an unknown number or a quantity that can change.
    • Coefficient: A numerical factor multiplied by a variable (e.g., in 5x, 5 is the coefficient).
    • Constant: A fixed numerical value that does not change (e.g., in 3x + 7, 7 is the constant).
    • Expression: A mathematical phrase containing numbers, variables, and operators without an equal sign (e.g., 2x + 4).
    • Equation: A mathematical statement asserting that two expressions are equal using an equal sign (=).
    • Polynomial: An expression consisting of variables and coefficients combining addition, subtraction, and non-negative exponentiation.
    • Exponent (Power): A number indicating how many times a base number or variable is multiplied by itself.
    • Function: A relationship between inputs and outputs where each input maps to exactly one output ($f(x)$).
    • Inequality: A relation comparing two expressions using inequality symbols ($<$, $>$, $\le$, $\ge$, or $\ne$).
    • Matrix: A rectangular array of numbers arranged in rows and columns used to solve linear systems.
