WAIT THATS THE SAME GUY?
Ben’s reading speed is faster than light 😂
they get the problem a few seconds before we do
my bad, exactly 1 second. like probably exactly one second, I went through the timer using the , and . buttons. we get the problem 60 frames after they do. since they said ten seconds at 20:39, the problem must have appeared at 20:04, but we got it 60 frames after that so a second later
Ben was really really good.He deserved to be in the finals.
"A couple minutes" I broke out laughing.
that loop worthy video is important videos worthy
Finding the sum of the reciprocals of the factors of 48 can be found like this 48 = 2^4 * 3^1 [ ( 1 + 2 + 2^2 + 2^3 + 2^4 ) / 2^4 ] * [ ( 1 + 3 ) / ( 3 ) ] = [ (2^5 - 1 ) / 2^4 ] * ( 4 / 3 ) = 31 / 12
Reading key words. All he sees is: cutting ribbon -> 15 -> one-third -> how long should = 5. The rest is just details.
LET'S GO NATHAN
Which one
I love how they added that classic chicken rabbit!
2:08 nathan's laugh
12:31 first thing national champ does: checks his pencil
Why does this not have as much viewership as the spelling bee competitions?
It's hard to defeat 1.3 billion people in youtube views 😂
Luke is an icon
i am still in the first question
radius 1 inch diameter 2 inches + 1 1 2 2 2+2=4+1=5
26:36 The data of the problem were wrong. The official answer is 54, so L=36 and W=18.
Hence the area of the black region is (36-4)*(18-4)=448...not 416.
No, the data were right, the area of the black region is 36*18=648, the area of both regions together is
(36+4)*(18+4)=40*22=880, the area of the white region is 880-648=132 and 132 is exactly 416 less than 648, as described.
Chemical Brother How did you come to that answer?
they say 416 is the difference in areas
This is Way Better than Spellbee
and also what is nathan hu laughing about?
ohhhh
sheeeeeeeeesh
The quality is really bad :(
2:01 didnt even get to see the question
i don’t understand why i’m watching these. i sucked at math in school. went to summer school just to graduate high school and college was a little better i guess but for some reason I CANT STOP WATCHING THESE COMPETITIONS
no one asked for your depressing life story
Ben had definetly deserved that ,just unluck
wooooo colin tang and edward wan
2 foot 416 ft 2
godsend speed, I can do almost all of these under 30 seconds, but the speed they do it at is ridiculous
is he Benq from Codeforces??
yup
1 inch
2 km/h 6km 12 km 6km 1 hour 45 minutes
2 km/hr 1 hour 45 minutes 12 km 2km 2km 6 km 2 km 12 km 4+2=6
24
5
6 km
(V_k = velocity. V_1 being the velocity of the first 6km. V_2 being the last 6km.)
We have v_2 = v_1 + 2.
So,
(V_1 + V_1 + 2)/2 = 12/1.75 = 12/(7/4) = 48/7 ---> V_1 = 41/7. Which is very close to 6 but not quite.
Incorrect again. v must verify 7/4 = 6/v + 6/(v+2), you speak too fast
It’s 6 guys

So difficult

Who are you talking to
Luke?
Don't underestimate benq he is 8th grade, while Luke is not qualify 6th grade
heheheha
11:00 , The greatest possible value of (n+1)!/n^(n-1). The answer is wrong! They said 3. But the correct answer is obviously 2.
aeroO bics 3 is obviously correct 3!/2
its asking for greatest possible value of the expression, not the value of n resulting in the greatest possible value of the expression. n = 2 gives you 3. 3 is the greatest possible value.
No Luke 0/10
wtf? get your fanboy out of here? boohoo he wasn't in 6th grade to qualify
The guys seem very inconsistent, clever one second but very weak the next.
Jack Ward They’re better than you at least
when would u say they were weak?
