What was the number trick the kid did at the table again? I wanted to do it but forgot
I almost freaked when I first did this with the movie because the # I thought of actually was 3 , so at first I thought it was like a psychological 'most people pick 3' thing, but then rewatched it and did it with different numbers.
You can think it mathematically as well. X is the number we are looking for.
(2x + 6):2 - x = 3 =>
(2x + 6):2 - x - 3 = 0 =>
x + 3 - x - 3 = 0
That should work in every number. It was put a bit difficult way in the movie though. When you see it mathematically you will see that there are only two pairs of terms. One pair x and -x and the other pair is 3 and -3. Those pairs neutralize each other.
it works! math is so weird!!!!! im amazeed
