What procedure is the same as multiplying a whole number by 1,000

The equivalent of multiplying 1000 to any number, is to add 3 zeros at the end of the number. That's the easiest way!

Suppose, I have an number, which is 78. I can multiply it with 1000, in the normal multiplication system.

              7 8 
     X 1 0 0 0

            0 0 0 0
         0 0 0 0 X
      0 0 0 0 X X
 +      7 8 X X X

          7 8 0 0 0

Let's follow the more easier way. Let's see whether it produces the same correct result or not. 

So, now, try adding 3 zeros to 78. It makes 78000.

Yes, it matches! Hurrah! That means this easy procedure (system/method) is the same as multipllying any number by 1000. You see, it produces the same result.

ANSWER: Adding 3 zeros to the end of any number is the same as multiplying it (any number) by 1000.
