Get back to me when you can imply a single rotation corresponding to

pathetic pleas and I don't do those. -

Leave your house and drive. To the nearest roundabout. Leave the roundabout
by the same exit as you entered. Now you ave turned 180 degrees.

Try this again but go all the way round the roundabout and exit by the road
opposite the entry road. Now you've turned 360 degrees.
This is exactly analogous to the extra rotation that the Earth makes in
it's orbit of the sun.
There- that was easy wasn't it.
