4. The group builds a pattern different from the combination of the various forms of mathematical operation according to the characteristics of walking of the clock. By a group of the square table to create various patterns of interest:
.For example, the pattern of a combination of various forms of mathematical operations by the addition of a digit, 0 1 2 A not rotate,
B. The rotation 90 degrees
D C rotation 180 degrees rotation 270 degrees
model,,, A A A A
model,,, A B C D
