(Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)

1. Commutative Property Numbers can be added or multiplied in any order and the answer is still the same. Examples: Commutative Property of Addition: 3 + 2 = 2 + 3 a + b = b + a Commutative Property of Multiplication: 5(4) = 4(5) ab = ba 2. Associative Property When adding OR multiplying 3 or more numbers, they can be grouped in any way

The commutative property (order property) states that the order of numbers does not matter when you are adding or multiplying numbers. Students are introduced to the distributive property of multiplication, through decomposing a number, as a strategy for solving multiplication problems. Jim purchased 5 packages of muffins.
