Which property states that multiplying a sum by a number results in the same product as multiplying each addend by that number?

• A. Associative Property
• B. Distributive Property
• C. Commutative Property
• D. Additive Identity

Answer: (B)

The property that states multiplying a sum by a number results in the same product as multiplying each addend by that number is known as the Distributive Property. This property can be expressed mathematically as \( a(b + c) = ab + ac \), where \( a \) is the number that multiplies the sum \( (b + c) \). This illustrates that regardless of how the numbers are grouped in addition, the multiplication distributes over the addition. For example, if you have \( 2(3 + 5) \), you can either first add the numbers in parentheses to get \( 2 \times 8 = 16 \) or distribute the \( 2 \) to each term to get \( 2 \times 3 + 2 \times 5 = 6 + 10 = 16 \), leading to the same result. Understanding the Distributive Property is fundamental in simplifying expressions and solving equations, making it a vital concept in mathematics overall.
