What Property of Addition is this?
65 + 2 = 2 + 65
Correct Answer
B. Commutative Property of Addition
Explanation
The given equation, 65 + 2 = 2 + 65, demonstrates the commutative property of addition. This property states that changing the order of the numbers being added does not change the sum. In this case, switching the positions of 65 and 2 does not affect the result, as both expressions yield the same sum of 67.

Find the sum of the following
1.) 4 + 5 = 5 + 4
Correct Answer
B. 9
Explanation
The given equation states that 4 + 5 is equal to 5 + 4. This is a commutative property of addition, which states that the order in which numbers are added does not affect the sum. Therefore, the sum of 4 + 5 is equal to the sum of 5 + 4, which is 9.
3.
Is this an example of Zero Property of Addition?
9 - 9 = 0
Correct Answer
B. False
Explanation
The given equation, 9 - 9 = 0, is not an example of the Zero Property of Addition. The Zero Property of Addition states that adding zero to any number does not change the value of that number. In this equation, subtraction is being used, not addition, and the result is zero, not the original number. Therefore, it does not demonstrate the Zero Property of Addition.

17 + (4 + 5) = (_ + 4) + 5
Correct Answer
17
Explanation
The given equation is asking to find the missing number that when added to 4 and then 5, will give the same result as adding 17 and 9. The missing number can be found by subtracting 4 and 5 from both sides of the equation. This gives us the missing number as 17.
5.
If 7 + 4 is 11, then what is 4 + 7?
Correct Answer
D. 11
Explanation
The commutative property states that the order of numbers does not affect the result of addition. Therefore, if 7 + 4 is 11, then 4 + 7 will also be 11.
6.
It is a property of Addition wherein a number is added to 0 and the sum is the number itslef
Correct Answer
C. Zero Property
Explanation
The given correct answer is "Zero Property." This property states that when a number is added to 0, the sum is the number itself. In other words, adding 0 to any number does not change its value. This property is a fundamental concept in mathematics and is used in various calculations and equations.
7.
9
+ 7
___
Correct Answer
16
8.
4 + 7 = 7 + 4 = __
Correct Answer
11
Explanation
The addition property of numbers states that the order in which numbers are added does not affect the sum. Therefore, when adding 4 and 7, the sum is 11. Similarly, when adding 7 and 4, the sum is also 11.
9.
19 + 0 = 19, what proprty is this?
Correct Answer
B. Zero Property
Explanation
The given equation, 19 + 0 = 19, demonstrates the Zero Property. According to this property, when any number is added to zero, the sum is always equal to the original number. In this case, adding zero to 19 results in 19, confirming the Zero Property.
10.
Which of the following is an example of Zero Property?
Correct Answer
A. 19 + (-19) = 0
Explanation
The Zero Property, also known as the additive inverse property, states that any number plus its additive inverse (opposite) equals zero. In this case, 19 and -19 are additive inverses, so their sum is 0.
11.
9 + 9 = ___
Correct Answer
18
Explanation
The given equation 9 + 9 equals 18. When you add 9 and 9 together, the sum is 18.
12.
4 - 3 = __
Correct Answer
1
Explanation
The subtraction of 3 from 4 results in 1.
13.
4 + 9 = __
Correct Answer
13
Explanation
The sum of 4 and 9 is 13.
14.
19 + 0 = 0 + 19 + __
Correct Answer
0
Explanation
When we add 19 and 0, the sum is 19. On the other hand, when we add 0 and 19, the sum is also 19. Therefore, no matter the order in which we add the numbers, the result will always be the same, which is 19.
15.
15 + 5 = 5 +15 = __
Correct Answer
20
Explanation
The given equation states that 15 plus 5 is equal to 5 plus 15. This is a commutative property of addition, which means that the order of the numbers being added does not affect the sum. Therefore, the answer is 20.
16.
9 - 0 = 9, is this an example of Zero Property?
Correct Answer
B. No
Explanation
This is not an example of the Zero Property. The Zero Property states that any number multiplied by zero is equal to zero. In the given equation, subtraction is being used, not multiplication. Therefore, it does not demonstrate the Zero Property.
17.
9 - 9 = 9 +9, is this a Commutative Property?
Correct Answer
A. No
Explanation
The commutative property states that the order of the numbers does not affect the result of addition or multiplication. In this case, the equation 9 - 9 = 9 + 9 does not follow the commutative property because rearranging the order of the numbers changes the result. Therefore, the correct answer is no.
18.
( 9 + 9 ) + 8 = 9 + ( 9 + 8 ) = ?
Correct Answer
D. 26
Explanation
The expression (9 + 9) + 8 can be simplified by performing the addition inside the parentheses first. This gives us 18 + 8, which equals 26. Similarly, the expression 9 + (9 + 8) can be simplified by performing the addition inside the parentheses first. This gives us 9 + 17, which also equals 26. Therefore, both expressions are equal to 26.
19.
Is this a property of ADDITION?
4 + (-4) = 0
Correct Answer
A. True
Explanation
This equation demonstrates the property of addition known as the additive inverse. The additive inverse of a number is the number that, when added to the original number, results in zero. In this case, the additive inverse of 4 is -4, and when added together, they equal zero. Therefore, the statement is true.
20.
9 + 8 + 8 + 9 = 8 + 9 + 8 + 9, is this a Commutative Property?
Correct Answer
B. Yes
Explanation
Yes, the equation demonstrates the Commutative Property of Addition. This property states that the order in which numbers are added does not change the sum. In this case, regardless of how the numbers 999 and 888 are ordered on either side of the equation, the sum remains the same. Thus, this example showcases that you can rearrange the terms when adding, and it will not affect the result.
