In this mini-lesson, we will figure out why it is so and explore the world of the associative property of multiplication. As with the commutative property, examples of operations that are associative include the addition and multiplication of real numbers, integers, and rational numbers. $$(2 \times 7) \times 3 = 2 \times (7 \times 3)$$ For example: (2 x 4) x 5 can be changed into 2 x (4 x 5) Both expressions create the same result. From the above example and simulation, we can say that the associative property of multiplication is defined as the property of multiplication where the product of three or more numbers remains the same regardless of how the numbers are grouped. First solve the part in parenthesis and write a new multiplication fact on the first line. The associative property states that the sum or product of a set of numbers is … Example: Use commutative property of multiplication to rewrite 5 x 4 5 x 4 Answer: 4 x 5 Example: Use commutative property of multiplication to rewrite 6 x 3 6 x 3 Answer: 3 x 6 Example: What is the missing number in 9 x 4 = 4 x ____? Commutative, Associative and Distributive Laws. The associative property of multiplication let's us move / change the placement of grouping symbols. Now, doing the problem, 6 x (4 x 5), we are going to start with 4 x 5 = 20 because of our parentheses and then multiply 20 by 6 to get our final answer of 120. All three examples given above will yield the same answer when the left and right side of the equation are multiplied For example, 3 × 4 = 12 and 12 × 5 = 60 Also, 4 × 5 = 20 and 3 × 20 = 60 Warning! The Multiplicative Inverse Property. Look closely; we have not changed anything about the numbers or the operations. Identity Property of Addition: Any number plus zero is the original number. According to the associative property of multiplication, the product of three or more numbers remains the same regardless of how the numbers are grouped. What is the point of adding yet another property to remember? In math, the associative property of multiplication allows us to group factors in different ways to get the same product.
