O x always such the international man of mystery Do
- 00:23
we need to pull out our caracas multiplication nunchucks and
- 00:26
reveal the imager behind the mask Well it may look
- 00:29
like we're supposed to divide five hundred by point Oh
- 00:32
five here But hold on there's got to be a
- 00:34
better way The problem is actually asking us to find
- 00:37
a number That man of mystery acts yet right there

dividing five hundred by ten moves a decimal one place
- 01:03
to left You get fifty divided by ten squared It
- 01:06
moves it to places to left We had five And
- 01:10
then if we uh need four places to the left
- 01:14
well let's see What do we do there We've got
- 01:16
to move it from its original spot after the five
- 01:18
hundred point zero to get two point five so well
- 01:20
we have to divide five hundred by ten to the
