What do the right inverse and the right inverse in the Rubik's Cube mean?
Right-handed clockwise refers to the counterclockwise rotation of the right side and clockwise rotation of the upper layer, which is a Rubik's cube term, as follows:

1, upwind: the upper layer turns clockwise.

2. Right: Turn the right side clockwise.

3. Up and down: the upper layer rotates counterclockwise.

4. Right reversal: the right side rotates counterclockwise.

5. Up and down: the upper layer turns counterclockwise.

6. Forward and backward: the front side rotates counterclockwise.

7. Up: the upper layer rotates clockwise.

8. Forward: Turn clockwise forward.

Commonly used terms

1, n order: order refers to the number of blocks in the cube * * *. For example, a third-order Rubik's cube has three small squares on each side, and two adjacent rotating surfaces of a pyramid Rubik's cube have five squares, but the main body has only three squares, so it is also third-order.

2. Reduction: refers to the process of Rubik's cube from non-original state to original state.

3.SUB: The original text is "subtraction", which means "subtraction, less than", which means "less than XX seconds". Example: 3×3 cubic SUB30 indicates that the average speed is below 30 seconds. The calculation method is to remove the fastest and slowest scores after 5 times of timing reduction and take the average.

4.DNS: the abbreviation of "not started" refers to giving up a recovery opportunity and not starting recovery, that is, abstaining before starting.

5.DNF: the abbreviation of "unfinished". It means that the contestants feel that they can't finish the Rubik's Cube in a satisfactory time and declare their abstention, or press the timer and the Rubik's Cube can't be restored. There can only be one DNF (counted as the worst score) in five competitions with an average review. If there are more than two DNFs, the project is divided into DNFs on average.
