Why are some of you so mad? If the explanations are boring for you, just speed the video up. You chose to watch it, right? It's not as if your boss is ranting your brain to pieces but you can't show it or just leave. THAT is torture.
Thank you 😂 I get their point, some of them just want to see the trick, but I have performed this trick many many times, so I found it worthwhile to include advisement on the performance of the trick and how effective it can be
It's a bit more complicated. As shown in the video, it's x + y + (x+y) + (x+2y) + (2x+3y) + (3x+5y) + (5x+8y) + (8x+13y) + (13x+21y) + (21x+34y) = 11(5x+8y)

@@lukas-0614 The fibonacci sequence works by adding the last 2 numbers, regardless of what numbers you picking it'll follow the same pattern of the 7th number being 1/10th the sum of all.

Good info - thanks much - And, What possibly could make one think that ceaseless distracting repetitive background music while teaching mental math would be a good idea ?!? Why why why do people think there must be some kind of law that demands every video… documentary, tutorials, interviews, lectures, even the most serious intellectual presentation… must must must have backgrounds noise playing while the person is speaking ?
it has me beat too. I turn it off. I can watch an hour long video of a Brit handy man renovating his house. No talking, no noise, just the sound of the work. Very relaxing and he is a a genius to boot! This Yank just likes to flap his lips…Also the wavy hands!! But he is very young. However, I have tried that easy multiply by 11 method he mentions with another 3 digit number and it doesn’t work. I did it my way and also with a calculator to check the correct number. But the number I get doing it his way is way off.
Anyone with any intelligence is going to say that the total has something to do with the 2 numbers and it is just a math trick. They may not know exactly the math involved but you are then at a disadvantage trying to disprove that.
@@michelerusconi And this trick, when used in a performance, is pretty bad. From the moment where you instruct the audience member to perform sums of the previous numbers everyone will know that you will use some kind of formula. Good tricks are those where you have no clue how the performer did it - here the way how things are rigged is just too obvious.
@@michelerusconi But you also did not say it was a bad trick, and that in my opinion was the main point of the original post - not the usage of the word „trick“ on which your reply is focusing. Since I very much agree with the OP‘s sentiment I wanted to give support to it.
pretty good trick, thanks for the trick, by the way I will subscribe you, I knew this trick but I had forgotten about it because I had not used it for long time ,but you reminded me which is very good
Very good trick, but the second number fir example in this case 24 need to be always the double of the first number 12?? .....or the second number can be any number?? For example the first --> 9 and the second number for example 16 or 21?? Thx
my thoughts exactly. typical Yankee…if you can take 20 words instead of 10 to explain something, go for it. They like to hear the sound of their own voice!
Probably because I've done the trick a lot, so I made remarks about the presentation of the trick and explained details about performing it outside of just the mathematics.
Lol, well there are several common possibilities 1) teacher 2) student wanting to amuse his friends or impress his teacher 3) everybody likes a good party trick, bully me about the 'parties' i go to to think this is a good trick if you must, but I stand my ground!
@@WrathofMathThe 1) teacher once humiliated me in front of the clasroom, saying that i hold op his lesson, but i was rehabilitated later, bcz he teached something wrong. 🤣
The fact that you have 21 copies of 19 is just because you chose the second number to be twice the first number. (5x + 8y, with y = 2x, is 5x + 16x = 21x.) If you chose, say, 15 and 31, the 21 trick won't work.
@antonycornell6284 wdym it doesn't work with 19 and 38? 19+38+57+95+152+247+399+646+1045+1591 = 4389 = 399*11 = 19*21*11 It wouldn't work to multiply the 1st number by 21 as mentioned above if y != 2x, but he never explicitly mentioned the 21 multiplier, or if I missed it that doesn't mean the 11 multiple doesn't work? If you pick 1 and 3 you get 29*11 = 319 which is correct, even though 1*21*11 is not correct. No clue how you got that 399*11 is incorrect
Considering it took me longer than a second to finish reading the first 3 numbers in the thumbnail, I have doubts You proved me wrong you goddamn MASTERMIND
1+2+...+10 is not possible if you follow the directions of the trick. If you began with 1 and 2, the next number would be 3, and the one after that 5, and then 8, 13, 21...

It’s pure math. X+ 2X + 3x + 5x+ 8x + 13x + 21x + 34x+ 55x + 89x = 231x, which is 11 times 21x
It's a bit more complicated. As shown in the video, it's

did you create this account specifically to comment on this video
You over explain. Way too much talking. You said to add up all the numbers and get a total at least 5 times. Do the trick first then break it down.
Could you please make a series of videos about all the mental math tricks from this book?
buy the damn book
That would not be cool for the author of the book, and would probably be illegal.
That's good math!
That it is!

I' ll have to check it out!
You really shouldn't have put the 2nd number as a multiple of the 1st.
Why?
@@paulfrost8952 It actually made me think of one variable instead of two to understand the trick. The proof was easy enough though.

great math! Just a thought but I think you can be a bit more concise in each of your explanations :)
I’m good at drawing a blank!
Also it's just 1x+2x+3x+5x+8x+13x+21x so on, it's the fibonnaci sequence

A 2 min vid crammed into 12 mins. Yawn
my thoughts exactly. typical Yankee…if you can take 20 words instead of 10 to explain something, go for it. They like to hear the sound of their own voice!
12 minutes to explain something which could take 60 seconds.
Neat trick but how is this a 12 minute video!?
Probably because I've done the trick a lot, so I made remarks about the presentation of the trick and explained details about performing it outside of just the mathematics.
I just added up the seconds.
I tried this with 99 and 98 to start and it didn't work, am I doing something wrong?
Yes you did something wrong
Yes. The 7th number is 1279 and the total is 14069.

19 * 21= 399
399* 11 = 4389 ie your times 11 trick fails
Just curious, what 2 numbers did you start with?
19 and 38. The number you multiply by 11 is 21 times the starting number
The fact that you have 21 copies of 19 is just because you chose the second number to be twice the first number.
(5x + 8y, with y = 2x, is 5x + 16x = 21x.)
If you chose, say, 15 and 31, the 21 trick won't work.

Not surprising

I heard 10 numbers and knew what it was. I think this was on Scam School a long time ago
2 minutes in and I already give up. get to the point
Oh for fuxache get to the point!
not very nice!
Well, you just skip every other number, like 36, 96, 252, 660, then 1068 the ending number since there's the odd list
OMG This guy talks too much. Get to the trick already.
Has anyone ever heard of Exel? Upgradet since 1980, but still working today! 😅😂🤣
Considering it took me longer than a second to finish reading the first 3 numbers in the thumbnail, I have doubts
You proved me wrong you goddamn MASTERMIND
Hilarious since all you have to do is read the last three numbers (just to count up to the seventh)
What if they select zero (0) as the first or the first two numbers?
It does not work for 1+2+...10.
1+2+...+10 is not possible if you follow the directions of the trick. If you began with 1 and 2, the next number would be 3, and the one after that 5, and then 8, 13, 21...
Lemme try this
