What does the statement a x 1 = a demonstrate?

What does the statement a x 1 = a demonstrate?

• A. Commutative Property
• B. Identity Law for Multiplication
• C. Associative Property
• D. Distributive Property

Answer: (B)

The statement \( a \times 1 = a \) illustrates the Identity Law for Multiplication. This law asserts that when any number is multiplied by one, the result is that number itself. In this case, whatever value \( a \) represents, multiplying it by 1 leaves it unchanged, affirming that 1 is the multiplicative identity. This concept is fundamental in arithmetic and algebra because it highlights the role of the number 1 in multiplication. It helps establish a baseline understanding of identity elements in various mathematical operations, reinforcing that 1 retains the value of any number it multiplies. Understanding why this particular statement reflects the Identity Law distinguishes it from other mathematical properties. The Commutative Property concerns the order of numbers in addition or multiplication, while the Associative Property relates to grouping of numbers. The Distributive Property connects multiplication and addition but does not apply in this case. Thus, recognizing the key characteristics of each property clarifies why the Identity Law is the correct choice here.
