Which statement correctly describes the difference between expanded form and expanded notation?

• A. Expanded form is the product of the place values; Expanded notation is the sum of the digits' values.
• B. Expanded form is the sum of the digits' values; Expanded notation is the product of the place values.
• C. Expanded form and expanded notation are the same.
• D. Expanded form applies to decimals; Expanded notation applies only to integers.

Answer: (B)

Expanded form and expanded notation both show how a number is built from its place values by breaking it into parts that reflect each digit’s contribution. Expanded form writes the number as a sum of each digit times its place value (for example, 652 = 6×100 + 5×10 + 2×1). Expanded notation conveys the same idea in a sum of those parts, often written as 600 + 50 + 2 or as the same terms with plus signs between, making the contribution of hundreds, tens, and ones explicit. The key idea is the same: the number is the sum of its place-value pieces, highlighting how each digit contributes.
