Properties of Multiplication and Addition

The video tutorial covers lesson 5.3 on properties of addition and multiplication. It explains the commutative property, where changing the order of numbers does not affect the sum or product. The associative property is discussed, highlighting that changing the grouping of numbers does not change the result. The addition property of zero is introduced, stating that adding zero to a number leaves it unchanged. Finally, the multiplication properties of zero and one are explained, emphasizing that multiplying by zero results in zero, and multiplying by one leaves the number unchanged.

What does the commutative property of addition state?

• Changing the order of numbers changes the sum.

• Changing the order of numbers does not change the sum.

• Changing the order of numbers does not change the product.

• Changing the order of numbers changes the product.

Which of the following is an example of the commutative property of multiplication?

• 5 * 3 = 3 * 5

• 5 + 3 = 3 + 5

• 5 - 3 = 3 - 5

• 5 / 3 = 3 / 5

What does the associative property of addition involve?

• Changing the grouping of numbers

• Changing the numbers themselves

• Changing the order of numbers

• Changing the operation

In the associative property of multiplication, what remains unchanged?

• The grouping of numbers

• The order of numbers

• The product

• The operation

What is the sum of any number and zero according to the addition property of zero?

• Zero

• The number itself

• One

• The number plus one

Which of the following illustrates the addition property of zero?

• 7 + 1 = 8

• 7 - 0 = 7

• 7 * 0 = 0

• 7 + 0 = 7

What is the product of any number and zero according to the multiplication property of zero?

• The number itself

• Zero

• The number plus one

• One

Which of the following is an example of the multiplication property of zero?

• 5 * 0 = 5

• 5 * 1 = 5

• 5 + 0 = 5

• 5 * 0 = 0

What is the product of any number and one according to the multiplication property of one?

• One

• The number plus one

• Zero

• The number itself

Which of the following demonstrates the multiplication property of one?

• 4 + 1 = 5

• 4 - 1 = 3

• 4 * 0 = 0

• 4 * 1 = 4
