01. multiplication by 10s, 100s, and 1000s

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 =
