What happens in the product as you multiply a number by powers of 10 (10, 100, 1000, and so on)?
When you multiply a number by powers of 10 like 10, 100, or 1000, the number gets bigger. You add zeros to the end of the number. If you multiply by 10, you add one zero. If you multiply by 100, you add two zeros. If you multiply by 1000, you add three zeros.
