Place value refers to the value of a digit based on its position within a number. In our decimal (base-10) number system, each position represents a power of 10. For example, in the number 345:

- The **5** is in the "ones" place, so it represents **5**.
- The **4** is in the "tens" place, so it represents **40** (4 × 10).
- The **3** is in the "hundreds" place, so it represents **300** (3 × 100).

Each digit's place determines its contribution to the overall value of the number. Moving left increases the place value by powers of 10, while moving right decreases it.

4. Can you explain the place value of a number in a different base, like base-2 (binary)?
5. How does place value help in rounding numbers?

**Tip:** Knowing place value is essential for performing operations like addition, subtraction, and rounding efficiently.
