Rubik’s Cube Notation
To describe a rotation on the cube we use letters. That’s what we call the Rubik’s Cube Notation.
A single letter by itself means to turn that face clockwise 90 degrees.
A letter followed by an apostrophe means to turn that face counterclockwise 90 degrees.
A letter with the number 2 after it means to turn that face 180 degrees.
e.g. R U R’ U R U2 R’ U
There is an other commonly used notation where the uppercase mean a clockwise and the lowercase means counterclockwise turns.
e.g. R U r U R U2 r U
For the beginner’s method you just have to know the simple F (front), B (back), R (right), L (left), D (down), U (up) turns but there are more complicated moves for speedcubers which manipulate the middle layer or two layers at the same time or reorient the whole cube.
