Expanded notation is defined as where each digit is written as a product of its place value.

• A. Each digit is written as a sum of its place values
• B. Each digit is written as a product of its place value
• C. A number written in standard form
• D. A number written in scientific notation

Answer: (B)

Expanded notation shows what each digit truly contributes by turning each digit into a product with its place value, and then adding those products together. This reveals how the value of a number comes from both the digit itself and its position. For example, 5,308 becomes 5×1000 + 3×100 + 0×10 + 8×1. Each digit is expressed as a product with its place value, which is the core idea of expanded notation. The other forms—standard form and scientific notation—represent the number differently and are not what expanded notation uses.
