Properties of multiplication and addition

Questions and Answers

1.

Subtraction of whole numbers is associative.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Subtraction of whole numbers is not associative. Associativity means that the grouping of numbers does not affect the result. However, in subtraction, changing the grouping of numbers will result in different answers. For example, (5 - 3) - 2 is not equal to 5 - (3 - 2). Therefore, the statement is false.

Rate this question:
2.

The sum of two different whole numbers is always greater than either addend.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because when adding two different whole numbers, the sum will always be greater than either of the two numbers. This is because when adding two numbers, the sum is essentially combining the quantities of both numbers, resulting in a larger value.

Rate this question:
3.

The sum of two even numbers is always even.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
When two even numbers are added together, the result will always be an even number. This is because even numbers can be expressed as multiples of 2, and when two multiples of 2 are added, the result will still be a multiple of 2. Therefore, the sum of two even numbers is always even.

Rate this question:
4.

Division of whole numbers is commutative.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The division of whole numbers is not commutative. This means that the order in which the numbers are divided affects the result. For example, if we divide 10 by 2, we get 5. However, if we divide 2 by 10, we get 0.2. This shows that the division operation is not commutative for whole numbers.

Rate this question:
5.

5 (1) = 1 (5) is an example of associative property.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The given statement, 5 (1) = 1 (5), is not an example of the associative property. The associative property states that the grouping of numbers does not affect the result of the operation. In this case, the numbers are being multiplied, and switching the order of the numbers does affect the result. Therefore, the given statement does not demonstrate the associative property.
