Properties of Addition

The video tutorial introduces the properties of addition, including the identity, commutative, and associative properties. The identity property states that adding zero to a number does not change its value. The commutative property explains that the order of addends does not affect the sum. The associative property shows that the grouping of addends does not change the sum. Each property is explained with examples, and the video concludes with a summary of these properties.

What is the result called in an addition problem?

• Addend

• Sum

• Product

• Difference

In the addition sentence 25 + 12 = 37, what are 25 and 12 referred to as?

• Products

• Sums

• Addends

• Differences

What does the Identity Property of Addition state?

• Adding zero to a number gives zero

• Adding one to a number gives the same number

• Adding zero to a number gives the same number

• Adding zero to a number changes the number

Which of the following is an example of the Identity Property of Addition?

• 5 + 0 = 5

• 5 + 5 = 10

• 5 + 1 = 6

• 5 + 2 = 7

What is the format for the Identity Property of Addition?

• a + b = b + a

• a + 0 = a

• a + b = c

• (a + b) + c = a + (b + c)

If 5 + 0 = 5, which property of addition is being used?

• Distributive Property

• Identity Property

• Associative Property

• Commutative Property

What does the Commutative Property of Addition imply?

• The sum changes when the order of addends is changed

• The sum remains the same regardless of the order of addends

• The sum is always zero

• The sum is always one

Which of the following demonstrates the Commutative Property of Addition?

• 3 + 4 = 7 and 4 + 3 = 8

• 3 + 4 = 8 and 4 + 3 = 7

• 3 + 4 = 8 and 4 + 3 = 8

• 3 + 4 = 7 and 4 + 3 = 7

What is the format for the Commutative Property of Addition?

• (a + b) + c = a + (b + c)

• a + 0 = a

• a + b = b + a

• a + b = c

If 7 + 8 = 8 + 7, which property of addition is being shown?

• Identity Property

• Associative Property

• Distributive Property

• Commutative Property
