# Rubik’s Cube Notation

For the Advanced Notations click here.**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.

The widget below features a 3D cube to demonstrate these rotations, but unfortunately this is not yet supported in all browsers. If your computer can’t render this HTML5 Rubik’s Cube properly please see the one below.
