3. REVIEW from The YELLOW Cross
Look at the YELLOW face.
Match the YELLOW face with:
The single YELLOW center piece and follow the algorithm:
The YELLOW right angle corner and follow the algorithm:
The single YELLOW line down the middle row of the YELLOW face and follow the algorithm:

4. REVIEW from the YELLOW Face
Position the YELLOW cross so that it matches one of the following:
The LEFT corner closest to you (LEFT/FRONT/UP) has a YELLOW piece on the LEFT face
The LEFT corner closest to you (LEFT/FRONT/UP) has a YELLOW piece on the UP face.
The LEFT corner closest to you (LEFT/FRONT/UP) has a YELLOW piece on the FRONT face.
Use the algorithm:
Reposition and use the same algorithm until all UP face corners are YELLOW.

Make sure the YELLOW Face is the UP Face.
Look at the RED, BLUE, ORANGE, and GREEN faces.
Specifically, look at the TOP row corners of each face.
Find a face that has matching TOP row corners:
(A&B; B&D; D&C; or C&A)
Twist the TOP row so that the matching TOP row corners match the center piece color of the face.
Position the cube so that the matching TOP row corners and center piece are on the BACK face.
At positions A&B

If you cannot find matching pieces on the same face or diagonal, do the algorithm until you do have matching end pieces on the same face or matching diagonal corners.
Be sure to check for matches after every completion of the algorithm.

Find a face that has matching TOP row corners:
Twist the TOP row so that the matching TOP row corners match the center piece color of the face.
Position the cube so that the matching TOP row corners and center piece are on the BACK face.
If you do not have match TOP row corners on one face:
Twist the TOP row until one set of diagonal corners is in the correct positions.
When the matching TOP row corners or diagonal corners are in the correct position, follow the algorithm to solve for all the TOP row corners:

12. Review from this Lesson
To solve a problem, sometimes you have to approach it in a different way.
When solving for the YELLOW corners, if you can’t find a matching TOP row corners on one face, then you can find matching diagonal corners.
When solving for a math problem, if you can’t solve a problem one way, then a different approach might help you solve the problem better.
There are many different strategies to help solve math problems:
Guess and Check
Diagrams
Lists
Tables
Write an equation
Backwards (answer first, then show the work)
