Commutative Property of Addition and Multiplication

The video tutorial explains the commutative property of addition and multiplication. It demonstrates that the order of addends or factors does not affect the sum or product. Examples are provided for both addition and multiplication to illustrate this property. The tutorial concludes with a memory aid to help remember the commutative property as the 'change order' property.

What does the commutative property state about the order of numbers in addition and multiplication?

• The order of numbers only matters in addition.

• The order of numbers only matters in multiplication.

• The order of numbers does not affect the result.

• The order of numbers affects the result.

If you have the numbers 5, 1, and 9, which of the following sums is incorrect according to the commutative property?

• 9 + 5 + 1

• 1 + 9 + 5

• 5 + 9 + 0

• 5 + 1 + 9

Which of the following is a correct application of the commutative property of addition?

• 5 + 1 = 5 + 0

• 5 + 1 = 1 + 5

• 5 + 1 = 6 + 1

• 5 + 1 = 5 + 2

What is the result of 5 * 1 * 9 according to the commutative property of multiplication?

• 45

• 15

• 5

• 9

Which of the following demonstrates the commutative property of multiplication?

• 5 * 1 = 5 * 0

• 5 * 1 = 6 * 1

• 5 * 1 = 5 * 2

• 5 * 1 = 1 * 5

If you multiply 9, 1, and 5, which of the following products is incorrect according to the commutative property?

• 1 * 5 * 9

• 9 * 1 * 0

• 9 * 1 * 5

• 5 * 9 * 1

What is the product of 1 * 5 * 9 using the commutative property?

• 15

• 5

• 9

• 45

Which of the following is NOT an example of the commutative property of multiplication?

• 9 * 1 = 9 * 2

• 9 * 5 = 5 * 9

• 9 * 1 = 1 * 9

• 9 * 0 = 0 * 9

What is a good way to remember the commutative property?

• It is the 'change order' property.

• It is the 'different order' property.

• It is the 'fixed order' property.

• It is the 'same order' property.
