### Apply

Complete these number sentences.

1. $3\times10=\editable{}$3×10=

2. $30\times10=\editable{}$30×10=

3. $300\times10=\editable{}$300×10=

4. $3000\times10=\editable{}$3000×10=

Remember!

When we multiply by $10$10, our number becomes ten times bigger, so the digit moves to the next highest place, by moving left. When we divide by $10$10, our number becomes ten times smaller. so the digit moves one place right.
