9:26 The first digit is not always the first digit - simply because there may be a remainder when adding the first digit to the second. This is why you should work it right to left - not left to right.
This could be a great activity for a substitute teacher. The students will be impressed with the teacher. They could work together. They will be doing math. You can divide the class into small groups, have each do their 10 lines on different places on the white board while you relax. Or on paper at their desks, then transfer to the white board. (Good idea to have predrawn lines.) It's hands on, uses a good chunk of time, is impressive, and is interesting.
Did you just use a Sharpie on a White Board? Oh no! Permanent markers are very difficult to "erase". Dry erase markers are specially made for white boards.
If the sum of a set of 2 digits exceeds 9, the "write it down" method fails. However, the (X*10)+X will always work and it is easy to do in your mind..
You could do the right to left sum, lets say 156x11 . Sum the last digit with the previous one (6+5)=11, greater than 10, you got 1 to spare, now sum 5+1=6 add the 1 to spare, 7, 1 is the first digit and 6 the last one,resulting in 1716 😊

Many, many years ago I saw a math trick in a magic book which involved adding (or multiplying, I can't remember) two long numbers together very quickly. I think they were about 7 or 8 digits, but i don't think the exact number mattered. I can't remember how it was done now, but I know it was easy to do because after a few goes I could do it faster than someone using a calculator, and I'm no math genius. Could any of you guys remind me of the method please?
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
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)

It does work, you just need to resolve any carryovers afterwards if they exist. Your 456x11 example would go 4-9-11-6, which resolves to 4-10-1-6 which goes to 5-0-1-6, i.e 5016
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

Huh? I've genuinely performed this trick in literally 1 second. You look at the numbers, find the 7th (fourth from bottom) and multiply by 11. It usually takes longer than a second, but if the numbers work out nicely, 1 second is totally reasonable. If that 7th number is 432 for example, this trick will take me 1 second. There is significant set up which takes more than 1 second, but that is for the audience. The actual trick which is performed may take only a single second.
You're missing the point of the 1 second glance. You don't even have to comprehend the numbers you're "looking" at. You don't even have to look at them all-only the seventh, or fourth from the bottom. I'm guessing you're not all that smart LOL.

I heard 10 numbers and knew what it was. I think this was on Scam School a long time ago
Too much rhubarb
Yappity-yap introduction finally peters out at
The hell iwth it. He hasn't gotten around to it at 1:58. I'm outta here.
It’s a very long s
Holy crap it took this guy twelve minutes to explain and do a trick that easily could have taken less than half that time. Talk about over explaining.
it's called mathsplaining
919
Get on with it ffs
12 minutes to add in 1 second....true genius.....NOT!!!👎
cool
cool..
What if they select zero (0) as the first or the first two numbers?
Then all the numbers would be zero and the total would be zero. Easy to memorize and easy to add.
12 minutes to explain something which could take 60 seconds.
Why then did you watch it all? Just to complain? What a moron!
I love your enthusiasm, but I think you should talk less and get to the point… just a suggestion of course.
i got a gf wit this trick
Not surprising
Congrats!
Things never said in history of humanity 😂
Well, you just skip every other number, like 36, 96, 252, 660, then 1068 the ending number since there's the odd list
Plz get to the point!
Oh for fuxache get to the point!
not very nice!
Has anyone ever heard of Exel? Upgradet since 1980, but still working today! 😅😂🤣
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!

You lost me at the second number

@@geoffrogerson6240Yes, you’re absolutely right that is beyond my mathematical understanding. And that is why I wrote that. I know my shortcomings and my strengths.
But it has nothing whatsoever do with puberty, it has to do with a condition called dyscalculia.
I thank you very much for your compassion, understanding and empathy. And I must say that I admire your courage to speak out at my atrocity. It’s unforgivable. If ever we do meet, can I pet that high horse of yours that you sit upon and spreading goodwill upon your fellow man?

Not possible in 1 second. It takes longer than 1 second to read and think of that many items.
Huh? I've genuinely performed this trick in literally 1 second. You look at the numbers, find the 7th (fourth from bottom) and multiply by 11. It usually takes longer than a second, but if the numbers work out nicely, 1 second is totally reasonable. If that 7th number is 432 for example, this trick will take me 1 second.
There is significant set up which takes more than 1 second, but that is for the audience. The actual trick which is performed may take only a single second.
You're missing the point of the 1 second glance.
You don't even have to comprehend the numbers
you're "looking" at. You don't even have to look
at them all-only the seventh, or fourth from the
bottom. I'm guessing you're not all that smart LOL.
@@geoffrogerson6240
Not like you. We bow our heads in admiration
MathS. Not math
Says who?
@@randomstuff_seriouslyThe British, apparently.
What if the 7th number is 1?
Are you stupid??
Obviously you weren't paying attention because that would be fucking impossible if you followed his directions
It's more than obvious that you lack any understanding
of the content of this video. Are you maybe a grade-schooler?
Way too much talking! Too distracting.
Why then did you watch it all? Just to complain? Tsk, tsk.
@ How do you know if I watched it all? Jumping to conclusions!
with that condition is pretty obvious and lame

@@geoffrogerson6240 People like you makes this world a better place. Here you are on your own free time helping others, spreading kindness, compassion and understanding. You should have your own day, like MLK day or 4th of July, so we can celebrate your kindness. Let’s make February 30th “the Geoff Rogerson compassion day” 🥳
