100516 f(x) Krystal is good at math

[@imacutedoge]

rather than good at math, shes a quick thinker lol

[@darcyvarattre2721]

I agree And I was your 1000. like

[@linecrew6404]

She is just a good runner lol

[@nell9400]

Nah she is a good at math

[@alexally2769]

The problems were easy, yes, but what's amazing about this is the fact that she can still solve the math problems in 1-2 seconds just by looking at it once with all the adrenaline.

[@muhammadfajri1666]

Alex97s because thats so easy. I think I can solve it too like her.

[@にゃにゃちぇんちぇい]

Muhammad Fajri too bad you'll never be in dream team

[@hatersnottodayunlessugotja6259]

Stream SNSD's I Got A Boy uhm no , its really easy to solve especially if you memorized the multiplication table ,im a 6th grader and i can answer anything from the multiplication table just by looking at it.

[@hatersnottodayunlessugotja6259]

Randommz k​​ dude , multiplication is used in every topics in math , especialy when you're already in high school/college (calculus , algebra , geometry , etc. ) , as you get older , you should become better(except if you're already in 90's or something) , krystal is already an adult , so its not a surprise if she knows every answer in multiplication table , if you're an 18 yr old boy/girl and you still haven't memorize the multiplication table , that's uncool , my dad is 49 yrs old and he can still solve math problems better than me.

[@heyyo1510]

Alex97s It's basic math, easy, but she ran fast while doing that so it's still pretty impressive :">

[@vanessapandolfi3852]

meanwhile Jessica’s motto is “never run no matter how late you are” lmaooo

[@yyxytbz]

UWU Lol. I remember that Sooyoung wants someone who runs and said that we are the worst combination LOLLLLLL Jessica never runs

[@meadoremums]

😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆😆😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

[@kekw5153]

Bruhhhhh IM DED

[@Chikimsan]

Lmaoooo 🤣🤣😂😂

[@evetherisk9957]

“I’m stupid,she’s a follower,she never runs” what sooyoung said was so accurate😂

[@oohsehunn2525]

I think Krystal is good at everything lol

[@LYCANCLANTEAM]

Yep, she's so perfect

[@oohsehunn2525]

yup

[@ChowMeinWarrior]

OOH SEHUNN g

[@goldenhistory7072]

PERFECT😍

[@wkpabpmbo]

YES

[@angelaliang50]

Lol the sports nerves from the parents of Jess and Krystal all went to Krystal XD

[@quynhnhu1411]

well, that was why she said "My dad's a boxer, my mom's a gymnast, and my sister's SNSD Jessica" LOL

[@niiicole]

You clearly haven't seen Jessica dominate her other members in table tennis and shoot a jump shot in one of their pictorials 😂

[@quynhnhu1411]

Actually, I had seen it LOL She can be pretty fast, it just that she chooses not to LOL I just love how she lazily walks around

[@DesignGurl]

did you mean Jessica or Krystal, because they both do, it one of the reason why Krystal sometimes faint during performance...

[@krystalgems405]

jessica is pretty athletic. she just choose not to show it cause she's just lazy XD. she did soccer, good at table tennis, I'd seen her play volleyball on one of their photoshoots. and this may be just a chance but she dribbled a basketball while walking in heels and made a score. jungsis is so talented.

[@AnakRantau0311]

I'm impressed by her speed

[@PhuongBui-fm5te]

wow its more amazing when she looks like a skinny girl without doing anything hard but she's actually really sporty

[@blackpkerstr]

+Kims Kristin Both Jung sisters were born naturally athletic, just Jessica's too lazy and absolutely refuses to run most of the time.

[@chemikaela9133]

+blackpkerstr yes they were also born anemic making it hard for them to be active all the time.

[@echizenohchibi4455]

@@blackpkerstr nope Krystal is the only one who's athletic..krystal already said during her interview(i can't remember when and what interview) she said when they're fighting Jessica lost when it comes to physical because Krystal is good at sports and stronger but in strategy Jessica wins because Jessica always says that I'm your older sister and you're fighting with me? I'm gonna tell this to mom😂lol

[@Ltlltd]

Well duh she's f(x) member

[@sharmainejoy1416]

HAHAHAHAHAHHAA

[@heaventohell6815]

😂😂😂😂

[@vanillaraven2618]

😹😹😹😹

[@vonlcsn]

This make sense lol

[@nickson211]

Well she mastered f(x,y)

[@aidasucianipertiwi4628]

it's hard to solve math problem after you fast running tho. even if it's just a simple one. she's great

[@ninichan7037]

she can be the next heroine for maze runner ehehe

[@mustachelol5806]

Jiminis

[@stopp2604]

Heroine* people may think ur saying shes a drug

[@MeuPlanetaOtaku]

While Jessica is sleeping, Krystal is doing this, I love the contrast in their personalities xD

[@pixieboo3009]

I was so scared, she has anemia. I have one too, it hurts, sometimes I try to fight it but I ended up fainting, the good thing is she didn't faint tho, that would be bad, crushing against those things.

[@anisyarahelll]

Really? she has anemia?

[@anisyarahelll]

are we talking abaout jessica or krystal?

[@anisyarahelll]

i was asking about krystal.

[@parksaeron5499]

Somi Douma yeah I have that too

[@whimsiwitch]

anisya rahel Hey, you got your question answered. Don't be an ass :/

[@penguinlovaaaa]

LOL. I honestly think that "Krystal is a fast runner" or something would be a more suitable title. I seriously thought that she was going to do some hardcore math problems when I clicked on this. XD

[@xAngecielx]

lmao hardcore math problems..that would be tense as fk

[@Adiadoreboo]

lmao same I thought it was gonna be something really hard hajahhah

[@shreya446]

i mean, she must be pretty decent 😆

[@ryashairuna3838]

LOL Krystal can run fast, can jump high, can throw darts near at the bull's eye, can throw the baseball. Not including that she's F(x) Main Vocalist & She can speak English. Now she can solve math. What is she?!

[@zanjelo3273]

F(x) lead vocalist. But yes she's really amazing! Jung sisters are the best 💚😍

[@Brilleetoile]

[@marianabucheli5930]

I mean, she's in a group called f(x). Not surprised. Edit 1: Krystal dancing to Bop Beep is ICONIC.

[@iyu0920]

Aww minho saying: it doesnt hurt, it doesnt hurt~~

[@maryyaawagg4529]

What are you talking about ?

[@iyu0920]

Luisa W 0:30 minho is talking to krystal because he wants to encourage her to run faster and ignore the yellow things...

[@eileenteng7775]

It was Junho who said it doesn't hurt....

[@l2maxim]

[@timlee8729]

Stupid.....

[@alielaire2523]

[@timhuynh9368]

her running form is perfect! the way she raised her knees and swing her arms looked perfect

[@shofiyakholidaf6210]

Krystal is really cool.... :)

[@syimato]

Uploader have to change the title "Krystal is fast at running and thinking" then no one will argue i guess?

[@sameoldlove55]

She can run fast, figure skate, be good at math, speak perfect English, dance well, sing well, be good at acting, look pretty, dress in style. And she’s so young and rich. What is she??!! Omg

[@gurlykpop1080]

I LOVE how she gives everyone a high five but gives snsd Hyoyeon a hug XD

[@SAM-uk8nv]

they didn't test math they test her speed..damn you're so fast soojung ah

[@janeshepard2660]

If those were spikes and I were the one running to solve mathematic equations I'd be dead. I can't do math to save my life, I need time plus a piece of paper to be able to solve them.

[@onceuponatime4786]

athletic, beautiful, talented, great personality

[@kriszmooi]

She's so athletic. Her abs tel.. She even hold the Dream Team's record in long jump for girls.

I'm not impressed by her maths cause it's a very simple maths questions but damn I must say she's a quick thinker after all that adrenaline rush, if it was me I need some time to think before I can answer that lol 😂 By the way, she can really run 😂

[@0907gsapphire]

[@k-popcraze663]

Kang minhyuk oppa will be proud of her. Love and Stan both of them..

[@MAngie-kn2ez]

[@elmin82]

she's so athletic and smart too

[@chateau6468]

The problems were pretty simple. In our country, public schools have this math thing called "window card", where elementary students should solve 100 problems in each operation (a total of 400 problems) under 3-5 minutes (I'm not totally sure but from my memory I think it was 3 minutes).

[@brianlee84yearsago68]

15 power of 2 is 225 17 power of 2 is 289 Factor of 144x2• -169 is (12x-13) (12x-13) Can she answer graph y=12/81x+40 in at least 2 seconds?

[@sam-wu2ff]

What were the questions he asked ??

[@brianlee84yearsago68]

Do you know how to solve with the formula of the Epot in the consistent valence Force Field (CVFF) by solving D=54 b=2 H=289 and F=169 to find position x? That’s my question.

[@kenyanghe]

i think the title must be "Krystal is so goooood at speed running"

[@Chong1991]

THE SONG AT THE END WAS T-ara's Bo peep bo peep

[@ubix4287]

I think the name of the show was dream team

[@rafiqatul.aminah]
