commutative property (of addition and multiplication) :: states that the order of the numbers when adding or multiplying does not change the sum or product. ADDITION: a + b = b + a MULTIPLICATION: a * b = b * a associative property (of addition and multiplication) :: states that the grouping of numbers when adding or multiplying does not change the sum or product ADDITION: (a + b) + c = a + (b + c) MULTIPLICATION: (a * b) * c = a * (b * c) distributive property (of addition and multiplication) :: a(b*c) = ab + ac additive identity :: adding zero to the number does not change it EXAMPLE: a + 0 = a multiplicative identity :: multiplying any number by 1 does not change it EXAMPLE: a * 1 = a inverse :: the opposite; undoes a mathematical operation (e.g., subtraction undoes addition, division undoes multiplication) additive inverse :: when the additive inverse of a number is added to that number, the sum will be zero. EXAMPLE: a + (-a) = 0 multiplicative invers
