The Secret Behind Super Junior’s Number: 13

The Secret Behind Super Junior’s Number: 13.
ELF must know about the slogan: SuJu13 right?

Well here either Lee Sooman is a mathematician or its truly a coincidence, take a look:

Sorted from year, month, and date of Super Junior’s member birth, then:
Teuk: 07/01/1983
Heechul: 10/07/1983
Hankyung: 02/09/1984
Yesung: 24/08/1984
Kangin: 01/17/1985
Shindong: 28/09/1985
Sungmin: 01/01/1986
Eunhyuk: 04/04/1986
Donghae: 10/15/1986
Siwon: 02/10/1987
Ryeowook: 21/06/1987
Kibum: 08/21/1987
Kyuhyun: 03/02/1988

-------------

Judging from their YEAR of birth, add the last two digits:
Leeteuk: 83 …. 8 +3 = 11 ….1 +1 = 2
Heechul: 83 …. 8 +3 = 11 ….1 +1 = 2
Hankyung: 84 …. 8 +4 = 12 ….1 +2 = 3
Yesung: 84 …. 8 +4 = 12 ….1 +2 = 3
Kangin: 85 …. 8 +5 = 13 ….1 +3 = 4
Shindong: 85 …. 8 +5 = 13 …. 1 +3 = 4
Sungmin: 86 …. 8 +6 = 14 ….1 +4 = 5
Eunhyuk: 86 …. 8 +6 = 14 ….1 +4 = 5
Donghae: 86 …. 8 +6 = 14 …. 1 +4 = 5
Siwon: 87 …. 8 +7 = 15 …. 1 +5 = 6
Ryeowook: 87 …. 8 +7 = 15 ….1 +5 = 6
Kibum: 87 …. 8 +7 = 15 ….1 +5 = 6
Kyuhyun: 88 …. 8 +8 = 16 ….1 +6 = 7
Then add all the results obtained
2 +2 +3 +3 +4 +4 +5 +5 +5 +6 +6 +6 +7 = 58

5 +8 = 13

-------------

Now from their MONTH of birth:
Teuk: 07 …. 0 +7 = 7
Heechul: 07 … .0 +7 = 7
Hankyung: 02 …. 0 +2 = 2
Yesung: 08 …. 0 +8 = 8
Kangin: 01 … 0 +1 = 1
Shindong: 09 …. 0 +9 = 9
Sungmin: 01 …. 0 +1 = 1
Eunhyuk: 04 …. 0 +4 = 4
Donghae: 10 ….1 +0 = 1
Siwon: 02 …. 0 +2 = 2
Ryeowook: 06 …. 0 +6 = 6
Kibum: 08 …. 0 +8 = 8
Kyuhyun: 02 …. 0 +2 = 2
Same way of adding
7 +7 +2 +8 +1 +9 +1 +4 +1 +2 +6 +8 +2 = 58

5 +8 = 13

-------------

Finally, let you add up the months beyond the month of their birth
March (3) May (5) Nov (11) Dec (12)
0 +3 = 3
0 +5 = 5
1 +1 = 2
1 +2 = 3
3 +5 +2 +3 = 13
SuJu’s formula formula consists of the number 13!

-------------

Now see from the alphabet (A = 1, B = 2 etc …)
S.U.P.E.R.J.U.N.I.O.R
S =19
U =21
P =16
E =5
R =18
J =10
U =21
N =14
I =9
O =15
R =18
Add
S = 1 +9 = 10
U = 2 +1 = 3
P = 1 +6 = 7
E = 5
R = 1 +8 = 9
J = 1 +0 = 1
U = 2 +1 = 3
N = 1 +4 = 5
I = 9
O = 1 +5 = 6
R = 1 +8 = 9
The end result is 10 +3 +7 +5 +9 +1 +3 +5 +9 +6 +9 = 67

6 +7 = 13

Well is this a coincidence? :D
