Turns/rotations in an algorithm should be separated by spaces.
There are 6 faces on a cube. Each face is represented by a letter, according to where it is located.
These faces make the most sense when you hold the cube with one face parallel to the ground and one face facing you,
but algorithm pages will often display the cube so that you can see the front, right, and top faces.
The six faces are:
- F (Front) - the side facing you.
- U (Up) - the side facing upwards.
- R (Right) - the side facing to the right.
- B (Back) - the side facing away from you.
- L (Left) - the side facing to the left.
- D (Down) - the side facing downwards.
A turn of one layer of one of the six faces of the cube is written by adding a suffix to the face\'s name.
There are three possible turns that can be applied to a face, and all moves should be applied
as if you were looking at the face straight-on. Using the U face as an example, the following are possible turns:
- U - A 90-degree clockwise turn of the U face.
- U\' - A 90-degree counterclockwise turn of the U face.
- U2 - A 180-degree turn (either clockwise or counterclockwise) of the U face.
