 Question Answer Order of Operations P - parentheses E - Exponents M or P - Multiplication or Division, whichever comes first A or S - Addition or Subtraction, whichever comes first Commutative Property applies to only addition and multiplication, NOT subtraction or division EX: a + b = b + a OR a x b = b x a Associative Property (the parentheses are grouping symbols) applies only to addition and multiplication, NOT subtraction or division EX: (a + b) + c = a + (b + c) OR (a x b) c = a (b x c) Distributive Property distributes multiplication over addition EX: a (b + c) = ab + ac OR (ab + ac) = a (b + c) (This does NOT apply to subtraction or division; a, b, and c are rational numbers.) Evaluating Expressions That Contain Absolute Value: First, calculate any calculations inside the absolute value bars as if they were parentheses.
