Multiplying by 10, 100, and 1,000 is super easy! When you multiply by 10, you simply add one zero to the end of the number. Multiplying by 100 means adding two zeros, and multiplying by 1,000 means adding three zeros. Think of it like a shortcut to bigger numbers!
For example, $5 \times 10 = 50$, $5 \times 100 = 500$, and $5 \times 1000 = 5000$. See how the number of zeros matches the number in 10, 100, or 1,000? Let's put this into practice!
Match the term with its definition:
| Term | Definition |
|---|---|
| 1. Product | A. A number multiplied by itself. |
| 2. Factor | B. The answer to a multiplication problem. |
| 3. Multiple | C. The numbers you multiply together. |
| 4. Exponent | D. The base raised to a power. |
| 5. Power of 10 | E. 10, 100, 1000 |
