It is the binary function: f(x, y) = (y, -x)
3 quarters clockwise is 270 degrees clockwise or 90 degrees anti(counter)-clocwise
Yes, a 270-degree clockwise rotation is the same as a 90-degree counterclockwise rotation. When you rotate an object 270 degrees clockwise, you effectively move it 90 degrees in the opposite direction, which is counterclockwise. Both rotations will result in the same final orientation of the object.
270
A rotation of 270 degrees clockwise is equivalent to a rotation of 90 degrees counterclockwise. In a Cartesian coordinate system, this means that a point originally at (x, y) will move to (y, -x) after the rotation. Essentially, it shifts the point three-quarters of the way around the origin in the clockwise direction.

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.

It is 270 degrees clockwise from north.
There are 270 degrees between north and west
