Mingyu& #39;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 --

2000-1999 = 1 x 1 = 1 ; 25,956-1= 25,955

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& #39;m not a math genius so i find every way difficult https://abs.twimg.com/emoji/v2/... draggable="false" alt="😅" title="Smiling face with open mouth and cold sweat" aria-label="Emoji: Smiling face with open mouth and cold sweat"> but mingyu& #39;s way is a shortcut since you have to just calculate small numbers. Some may find mingyu& #39;s way easier but some may also find it more difficult. It depends on a person& #39;s tactic. Ghad I HATE MATH https://abs.twimg.com/emoji/v2/... draggable="false" alt="✨" title="Sparkles" aria-label="Emoji: Sparkles">

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.
