00:17

All right So what are they trying to do here

00:19

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
