something of the horse

From the hedge number’s: 

2-1= one

4-3= one

6-5= one

8-7= one

10-9= one

From the same root number’s: 

        New born number         Mature number

"New born number " is  1;2;3;4;5.

"Mature number" is     6;7;8;9;10.

（《same root number》 was born from five）.

【 one with six】     6-1=5        1-6=-5 

【 seven with two】  7-2=5        2-7=-5

【 three with eight】 8-3=5        3-8=-5

【 four with nine】   9-4=5        4-9=-5

【five with ten】     10-5=5       5-10=-5

(Same root numbers were born from 5).

6 – 1 = 5

2 – 7= -5 

8 – 3 = 5

4 – 9 = -5

5 – 5 = 0

∣6 – 1∣+∣2 – 7∣+∣8 – 3∣+∣4 – 9∣+∣5 – 5∣=zero

5+（-5）+0+ 5 +（-5）= Zero

5 +（-5）= Zero    5 +（-5）= Zero

No matter how you play it ,it would symmetry or balance（hedge）.For example

(4 fives except the center 5)

7+8=15 ；2+3=5 ┋ 4+1=5；9+6=15 

7+3+8+2=20┋4+6+1+9=20

2-1=1┋4-3=1

7-6=1┋9-8=1

(4 fives except the center 5)

7-2=5 ┋6-1=5

8-3=5 ┋9-4=5

     9-7=2    4-2=2   3-1=2    8-6=2

2+4=6 ┋1+3=4      4 with 6 hedge

7+9=16┋ 8+6=14   16 with 14 hedge

7+9+2+4=22  ┋ 3+1+8+6=18

22+18=40   22 with 18 hedge
