How To Solve a 2x2 Rubik's Cube

step 1 Notation
If you already know how to solve a 3x3 you can skip this part. This is notation when i say R the layer to your right is to be moved once clockwise. L is the left layer. U is the top side. D is the bottom layer.

If there is an (') after a letter you turn the side counterclockwise.

If you still do not explain look it up on google their should be a more thorough definition on Notation.

step 2 First Layer
First you must choose a layer. I will choose the Green side.
First find a green piece.
Then you find the piece that belongs beside it in my case I picked the green,white, and red piece. I must find a piece that has both green and red. There will only be one. Put this picture in the lower layer. Below where it actually belongs as in the picture. Then put it on the right side and do this algorithm (notations) R' D' R D

Find the next piece and finish the top layer.

step 3 Next Side
Now we will put what we have finished on the bottom. And work on the next side. Take note I say side here not layer. Because we will be just working on the top colors (blue for me) There is four total ways this can be arranged. If you have no blue colors on the top dont worry how you hold it just do this algorithm R U R' U R U2 R'
If you have 1 blue on top hold it like in the picture and then do the algorithm from above.
If you have 2 blue on top hold it like in the picture and then do the algorithm from above. Or the other way for 2.
If you have 4 on top you are lucky you have to do nothing

step 4 Finish cube
Now to finish take a look at the last layer. Find two colors that match up like my black ones here. Put them in the back then do the algorithm R' F R' B2 R F' R' B2 R2.
Now the cube is solved.
