A + b = b +a is an example of which mathematical property?
- A.
Commutative Property (Order Property)
- B.
Associative Property (Grouping Property)
- C.
Distributive Property
Correct Answer
A. Commutative Property (Order Property)Explanation
The given equation, a + b = b + a, demonstrates the commutative property of addition. This property states that the order of adding two numbers does not affect the sum. In other words, when adding two numbers, it doesn't matter which number comes first, the result will remain the same.Rate this question:

A + (b +c) = (a + b) + c is an example of which mathematical property?
- A.
Commutative Property (Order Property)
- B.
Associative Property (Grouping Property)
- C.
Distributive Property
Correct Answer
B. Associative Property (Grouping Property)Explanation
The given equation, a + (b + c) = (a + b) + c, demonstrates the Associative Property (Grouping Property) in mathematics. This property states that the grouping of numbers being added or multiplied does not affect the result. In this case, regardless of whether we first add b and c or a and b, the final sum will be the same. The equation shows that the addition of b and c is grouped together and then added to a, which is equivalent to adding a and b first and then adding c.Rate this question:

A x (b + c) = (a x b) + (a x c) is an example of which mathematical property?
- A.
Commutative Property (Order Property)
- B.
Associative Property (Grouping Property)
- C.
Distributive Property
Correct Answer
C. Distributive PropertyExplanation
The given equation, a x (b + c) = (a x b) + (a x c), represents the Distributive Property. This property states that when multiplying a number by the sum of two other numbers, you can distribute the multiplication to each term inside the parentheses. In this case, the multiplication of a by the sum (b + c) is equal to the sum of the multiplication of a by b and the multiplication of a by c.Rate this question:

What is the prime factorization of 120?
- A.
2 x 2 x 2 x3 x 5
- B.
10 x 12
- C.
2 x 2 x 5 x 6
Correct Answer
A. 2 x 2 x 2 x3 x 5Explanation
The prime factorization of a number involves finding the prime numbers that multiply together to give the original number. In this case, the prime factorization of 120 is 2 x 2 x 2 x 3 x 5. This means that 2, 3, and 5 are the prime numbers that, when multiplied together, equal 120.Rate this question:
