This document provides information about multiplying and dividing numbers by powers of ten. It explains that when multiplying, the decimal point moves to the right by the number of places being multiplied by. For example, when multiplying by 100, the decimal moves two places to the right. When dividing, the decimal moves to the left by the same number of places. The document also includes example multiplication and division problems applying these concepts.
