It is the binary function: f(x, y) = (y, -x)
3 quarters clockwise is 270 degrees clockwise or 90 degrees anti(counter)-clocwise
270
AB --clockwise-------------\ B C ----------------------------/ AC AB --counter-clockwise--\ CA C ----------------------------/ B
'Difference' is a mathmetical expression for subtraction. 7 #Hence 270 - 108 = 162 (The difference).
That's a total of 270 degrees.
270 rule represent a 270 rotation to the left which is very easy
3 quarters clockwise is 270 degrees clockwise or 90 degrees anti(counter)-clocwise
Minus 270 degrees which is equivalent to a quarter anti-clockwise turn, or +90 degrees.
Move it 3 times* * * * *or once in the anti-clockwise direction.
90 + 360*k degrees anti-clockwise for any integer k.
270
Both will end up on the same place. Using a compass rose as an example: 270 clockwise will point to the west. 90 counterclockwise will also point west.

Rotation of 270 degrees clockwise or 90 degrees counter clockwise
It is 270 degrees clockwise from north.
There are 270 degrees between north and west
You dont, its just 90 degrees 3 times..
