Example

Multiplying $2.58$ by Powers of Ten

To multiply $2.58$ by powers of ten, we move the decimal point to the right by the same number of places as there are zeros in the power of ten:

Multiplying by $10$ ( $1$ zero) requires moving the decimal point $1$ place to the right, resulting in $25.8$ .
Multiplying by $100$ ( $2$ zeros) requires moving the decimal point $2$ places to the right, resulting in $258$ .
Multiplying by $1000$ ( $3$ zeros) requires moving the decimal point $3$ places to the right, which means adding one zero at the end to get $2580$ .
