### Rule

When you multiply a number with a **10**, you just put **one zero** next to that number. When you multiply a number with a **100** you put **two zeros** next to that number. And when you do similar with a **1000** you put **three zeroes** and so on and so forth.

### Example

7 X 10 = 70 7 X 100 = 700 7 X 1000 = 7000

### You try with 10s

25 X 10 = 67 X 10 = 245 X 10 = 200 X 10 =

### You try with 100s

25 X 100 = 67 X 100 = 245 X 100 = 200 X 100 =

### You try with these

25 X 1000 = 67 X 10 = 245 X 100 = 200 X 100000 =
