Basic Notations of 3 by 3 Rubik's Cube.

 The 3x3 Rubik's Cube uses a set of notations to represent the different moves and rotations you can make. Here are the basic notations for the Rubik's Cube:

  1. 1. Face Rotations:

    • F: Rotate the Front face 90 degrees clockwise (a quarter turn).
    • F': Rotate the Front face 90 degrees counterclockwise (an inverse or prime move).
    • F2: Rotate the Front face 180 degrees (a half turn).

    Similarly, you can apply the same notations to the other faces:

    • R: Right face
    • R': Right face counterclockwise
    • R2: Right face 180 degrees
    • U: Upper face
    • U': Upper face counterclockwise
    • U2: Upper face 180 degrees
    • L: Left face
    • L': Left face counterclockwise
    • L2: Left face 180 degrees
    • B: Back face
    • B': Back face counterclockwise
    • B2: Back face 180 degrees
    • D: Down face
    • D': Down face counterclockwise
    • D2: Down face 180 degrees

  2. 2. Slice Moves:

    • M: Middle slice, a vertical slice between the R and L faces.
    • M': Middle slice counterclockwise.
    • M2: Middle slice 180 degrees.
    • E: Equator slice, a horizontal slice between the U and D faces.
    • E': Equator slice counterclockwise.
    • E2: Equator slice 180 degrees.
    • S: Standing slice, a horizontal slice between the F and B faces.
    • S': Standing slice counterclockwise.
    • S2: Standing slice 180 degrees.

These notations allow you to describe all the possible moves and combinations that can be used to solve the Rubik's Cube. By learning and using these notations, you can follow various solving methods and algorithms to solve the cube efficiently.

Learn to solve a Pyraminx.

  Solving a Pyraminx can be done using a methodical approach. Here's a basic step-by-step guide to solving a Pyraminx: Step 1: Understand the Pyraminx Notation Before you start solving, familiarize yourself with the Pyraminx notation: U - Rotate the upper face clockwise. U' - Rotate the upper face counterclockwise. R - Rotate the right face clockwise. R' - Rotate the right face counterclockwise. L - Rotate the left face clockwise. L' - Rotate the left face counterclockwise. B - Rotate the back face clockwise. B' - Rotate the back face counterclockwise. Step 2: Solve the Tips Begin by solving the tips of the Pyraminx. This involves matching the colors on the tips with the center color of each face. You can do this by turning the tips until the colors match. Step 3: Solve the First Layer Once the tips are solved, move on to solving the first layer. This involves solving the three triangular pieces surrounding the center. Follow these steps: Choose a Color : Pi...

Learn how to solve a 5 by 5 Rubik's Cube.

  Solving a 5x5 Rubik's Cube is similar to solving the 3x3 Cube, but it involves some additional steps due to the increased complexity. Here's a basic guide to solving a 5x5 Rubik's Cube, also known as the Professor's Cube: 1. Solve the Centers: Start by solving the center pieces of each face. This is relatively easy as these pieces don't move. Focus on getting one center color on each face. 2. Pair the Edges: Pair up the edge pieces with their corresponding colors to create "edge pairs." Unlike the 3x3, you may have to deal with more than one piece per edge. 3. Solve the First Two Layers (F2L): Similar to the 3x3, solve the first two layers by pairing up the edge and corner pieces to create complete "F2L pairs." This might involve pairing an edge from one layer with a corner from another layer. 4. Pair the Last Edges (L4E): Pair up the last remaining edge pieces. This step may require some advanced techniques. 5. Solve the Last Two Centers: Now,...
