# How to Understand Rubik's Cube Algorithm

Many people don't understand what the letters and symbols in the algorithm represent? Then I will give you a table first, and see if you understand it~

F = Front

B = Back

R=Rigth

L=Left

U = Up

D = Down

OK, which direction should I turn next~ I believe everyone is still clear clockwise and counterclockwise~

Clockwise 90 degrees 　=representing letters <for example: R means rotate 90 degrees clockwise on the right>

90 degrees counterclockwise 　 = representative letter + "’" <R'means that the right side rotates 90 degrees counterclockwise>

180 degrees clockwise = representative letter + "2" <R2 is 180 degrees to the right>

180 degrees counterclockwise = representative letter + "’2" <R'2 is the same as above~ you will find that you can turn it when you turn 180 degrees~ ha ha>

What kind of XYZ will appear in other formulas, I will also write it down for everyone~

x: (the whole Rubik's cube rotates in the direction of R), x': (the whole Rubik's cube rotates in the direction of R')

y: (the whole Rubik's cube rotates in the direction of U), y': (the whole Rubik's cube rotates in the direction of U')

z: (the whole Rubik's cube rotates in the direction of F), z': (the whole Rubik's cube rotates in the direction of F')

Well, with these, I should introduce the restoration~~ I will not introduce you to the layer first~ Most of you will not use this method quickly?

Then I will introduce the Fridrich method

Fridrich method is fast completion method

This method is the most popular fast reduction method today, Fridrich method.
There are four steps to complete the method: CROSS－>F2L->OLL->PLL

CROSS: It means the cross (of course, the first cross is built first).

F2L: It means First Two Layer (the first two layers).

OLL: It means ORIENT Last Layer, which means to reverse all the colors of the last layer.

PLL: It means the POSITION Last Layer, which means that all the edges and corners of the last layer are exchanged.
