How to add those numbers quickly in 15 seconds like that person in the show?University War (Korea), and Clash of Champions (Indonesia) is a mathematic TV shows competition currently very trending in respective countries (especially for women lmao).Genius Korean/Indo college students around the world (including Harvard, etc) gather in this competition to prove who is smarter at solving problems with pure brain power.compare your brain rawpower with those top 0.0001% of students here:https://universitywar.comDoes calculating numbers every day make us faster at it?Does the abacus lesson worth it?
>>16263420Do hyun (SNU strategist) gave the math trick for this cube problem.He use lorentz hand but in left hand.But i don't understand how it work.Rock=middle fingger, paper=thumb, scizzor=point finger.https://universitywar.com/games/rps
>>16263420About prime numbers, we can remove the multiply of 3 by adding the numbers.For example 1113 is a multiply of 3 because 1+1+1+3 is a mod of 3.But how do hyung bin know the middle number perfectly?https://universitywar.com/games/prime

>>16263420You can easily get a best case estimation by simply looking at them.Each term is exactly 3 digits long. There are 10 terms (this should be either immediately visible, or you can count them, shouldn't take more than 2 seconds).Without any calculation, probalistically each term should be around 500. This gives you already an estimation in the vicinity of 5000.Now with the remaining 12 or so seconds, you refine it. How many terms are above 500, how many below? How much?Don't calculate the least significant digits. Who gives a shit? Dumbass autists do.
>>16263420My computer can do it in a fraction of a milisecond
Add the 100s, then the 10s, then the ones. This is simple. You guys are joking right?
