In our Base 10 math system, we know that all the digits slide to the left one column when you multiply by 10. Conversely, the digits slide one column to the right when you divide by 10.

The question is: WHY?

Why does 0.001 x 10 = 0.01?!

Why does 0.001 ÷ 10 = 0.0001???

Watching the videos below will help you understand. Be sure you have your volume turned on.  🙂
