Step 3: How to Solve: Cube Notation
You should be familiar with turning notation. If you are a little rusty here is a quick reminder:
U – turn the top face clockwise
F – turn the face in front of you clockwise
R – turn the face on the right clockwise
L – turn the face on the left clockwise
D – turn the bottom face clockwise
Note: Adding an apostrophe denotes a counter-clockwise turn (D’) and adding a two denotes a 180 degree turn (D2). All moves are made imagining you are facing that layer.
