# Rubik's Cube Tricks-center piece.

## Step 1: Notation

Before you start, you will have understand some basic notation, or these steps will confuse you.

F = Front (the side that faces you)
B = Back(the side that faces away from you)
BT = Bottom(The side that faces down)
R = The right side
L = the left side

* = Inverted. This goes after a side abbreviation, and it means that you turn the specified side counter-clockwise, as if it were facing you .
This is very important, because if you reverse the direction for which you turn the side, it can mess you up.

Example: Ri = Right side, inverted (counter-clockwise)
D = Down (clockwise)

These notations make up Algorithms which sounds fancy and smart, but is actually quite simple. (You can impress your friends by saying that you used and algorithm to solve this.) An Algorithm is just a set of rules used in problem solving. To solve this, you will use four algorithms, each made up of two corresponding  movements. As you will see, the algorithms use one inverted movement, and one standard movement of the opposing side. Algorithms in this project are grouped together using parenthesis (), much like coordinates on a graph.

For example, in the first algorithm, (Ri, L), You turn the right side counter-clockwise, and you turn the opposing side clockwise.

List of algorithms.

(Ri, L)
(Bi, F)
(Ui, D)
(Ri, L)

The first and last algorithms are the same, and you must repeat them as shown.

Or you can just do M and E moves over and over (google it if you don't know what they are)

Sorry for the bad picture quality. My camera wouldn't focus.

nice, although i already knew how to do this :)
