<image>Given a number axis on paper (as shown in the figure).

Operation One:
(1) Fold the paper so that the point representing the number 1 coincides with the point representing the number -1. At this moment, the point representing the number -2 coincides with the point representing the number ____.
Operation Two:
(2) Fold the paper so that the point representing the number 5 coincides with the point representing the number -1. Answer the following questions:
① The point representing the number 6 coincides with the point representing the number ____.
② If after folding in this way, there are points A and B on the number axis that also coincide, and the distance between points A and B is 11 (A is to the left of B), then the number represented by point A is ____, and the number represented by point B is ____.
