  21. Associative Prop of Addition
    changing the grouping of the numbers in a sum does not change the sum

    Ex: (9+6)+2 = 9+(6+2)
  22. Associative Prop of Mult
    changeing the grouping of the numbers in a product does not change the product

    Ex: (3x10)x4 = 3x(10x4)
  23. Commutative Prop of Add

  24. Commutative Prop of Mult
    in a product, you can multiply the numbers in any order

    Ex: 8(-5) = -5(8)
  25. Distributive
    a(b+c) = ab + ac
  26. Addition Prop of Equality
    adding the same number to each side of an equation produces an equivalent equation
  27. Multiplication Prop of Equality
    multiplying both sides of an equation by the same number produces an equivalent expression
  28. Element
  29. Union
