    Basic Properties of Real Numbers:

    Given that X, Y, Z, A, B, C, and D are real numbers, then the following are true:

    Commutative Property of Addition: X+Y = Y+X

    Commutative Property of Multiplication: XY = YX

    Associative Property of Addition: (X+Y) + Z = X + (Y + Z)

    Associative Property of Multiplication: (X Y) Z = X (Y Z)

    Additive Identity: For any real number X, X+0 = X where 0 is the additive identity

    Additive Inverse: For any real number X, there exists - X such that X + (-X) = 0

    Multiplicative Identity: For any real number X, 1●X = X where 1 is the multiplicative identity

    Multiplicative Inverse: For any real number X where X≠0, there exists 1/X such that X ● (1/X) = 1

    Zero Product Law: If XY = 0, then X=0 or Y=0 or both X and Y = 0
