2.

Which property is shown by (a + b) + c = a + (b + c)?
- Identity
- Distributive
- Commutative
- Associative
Correct Answer

A. Associative

Explanation

The associative property is crucial for both addition and multiplication. It states that no matter how numbers are grouped within an operation, the result will be the same. In the case of addition, (a + b) + c equals a + (b + c). This property allows for the regrouping and rearrangement of terms in an expression, facilitating simpler computation, particularly in more complex algebraic expressions.

3.

When a * (b + c) = a * b + a * c, it illustrates the ___ property.
- Associative
- Distributive
- Commutative
- Identity
Correct Answer

A. Distributive

Explanation

The distributive property is a fundamental property that bridges addition and multiplication. It states that a single number multiplied by a sum of two or more numbers inside a parenthesis equals the sum of the individual products. For example, a * (b + c) results in (a * b) + (a * c). This property is particularly useful in algebra for expanding expressions and simplifying calculations involving parentheses.

4.

Which property describes a * 1 = a?
- Zero Property
- Identity Property
- Multiplicative Identity
- Distributive
Correct Answer

A. Multiplicative Identity

Explanation

The multiplicative identity property states that any number multiplied by one retains its original value, a * 1 = a. This property is one of the basic identities in arithmetic and algebra, reinforcing the concept that the number one is the neutral element for multiplication. It plays a critical role in preserving the identity of elements during operations and in solving equations.

5.

If a + 0 = a, which property is being used?
- Additive Identity
- Multiplicative Identity
- Distributive
- Associative
Correct Answer

A. Additive Identity

Explanation

The additive identity property specifies that any number plus zero will result in the original number, a + 0 = a. This is because zero is the identity element for addition; it does not change other numbers. This property is essential in simplifying expressions and solving equations, as adding or subtracting zero does not alter the value.

6.

What does the Inverse Property state about addition?
- A + (-a) = 1
- A + (-a) = 0
- A * (-a) = 1
- A * a = 1
Correct Answer

A. A + (-a) = 0

Explanation

The additive inverse property demonstrates how every real number a has an inverse, denoted as -a, such that when added together, the result is zero, a + (-a) = 0. This property is fundamental in solving equations, allowing for the cancellation of terms to isolate variables and solve for unknowns effectively.

7.

Which property defines a * (b * c) = (a * b) * c?
- Commutative
- Associative
- Distributive
- Additive Identity
Correct Answer

A. Associative

Explanation

The associative property for multiplication states that when three or more numbers are multiplied, the product is the same regardless of their grouping, hence a * (b * c) = (a * b) * c. This property ensures consistency in the multiplication process, allowing for the numbers to be grouped differently for ease of calculation without affecting the outcome.

8.

If a + b = b + a, this property is called ___?
- Associative
- Distributive
- Commutative
- Identity
Correct Answer

A. Commutative

Explanation

The commutative property for addition indicates that two numbers can be added in any order without changing the result, a + b = b + a. This property provides flexibility in how terms are arranged within an equation or expression, simplifying calculations and making the operations more intuitive.

Rate this question:

1
9.

The equation a * (1/a) = 1 uses what property, if a ≠ 0?
- Additive Inverse
- Multiplicative Inverse
- Distributive
- Associative
Correct Answer

A. Multiplicative Inverse

Explanation

The multiplicative inverse property ensures that every non-zero number a has an inverse 1/a, such that a * (1/a) = 1. This is crucial for solving equations involving division and multiplication, allowing numbers to be manipulated algebraically to isolate and solve for variables, effectively 'undoing' multiplication.

Rate this question:
10.

For all real numbers a, b, and c, if a(b + c) = ab + ac, it confirms the ___ property.
- Associative
- Identity
- Commutative
- Distributive
Correct Answer

A. Distributive

Explanation

The distributive property's confirmation through a(b + c) = ab + ac highlights its role in distributing a multiplication over an addition inside a parenthesis. This property is key in algebra for expanding expressions, simplifying complex algebraic operations, and ensuring uniform application of operations across terms within parentheses.
