Mingyu's sexy brain got me in this part. The question is what is the sum of the year of birth of all members? The sum is 25,955.
As a normal thinker you would calculate one by one by adding the sum of how many member was born each year. Instead he calculate in a different way--

Mingyu assumed all were born at 2000 and multiplied it by 13. He got a total of 26,000. If you were born in 1995, 2000 minus 1995 is 5 multiply by how many members born in that year which is 3, the answer is 15. Then he minuses 15 to 26,000. Same goes to other years until he--
come up to the final answer of 95,955.
Mathematical calculations in this way..
2000x13 = 26,000
2000-1995 = 5 x 3 = 15 ; 26,000-15= 25,985
2000-1996 = 4 x 4 = 16 ; 25,985-16= 25,969
2000-1997 = 3 x 3 = 9 ; 25,969-9= 25,960
2000-1998 = 2 x 2 = 4 ; 25,960-4= 25,956 --

His way is more difficult yet he calculate smartly at the given time and THAT WAS ONE REAL SEXY BRAIN!!
NO DOUBT HE GOT THAT TITLE.

I'm not a math genius so i find every way difficult 
but mingyu's way is a shortcut since you have to just calculate small numbers. Some may find mingyu's way easier but some may also find it more difficult. It depends on a person's tactic. Ghad I HATE MATH

Lastly, Happy Birthday, Mingyu!

Mingyu pretty much solved like this mentally during the game. I just thought of it, this explanation is way more easy to understand how he solved.
2000x13= 26,000
5x3= 15
4x4= 16
3x3= 9
2x2= 4
1x1= 1
15+16+9+4+1= 45
26,000-45= 25,955.
