no efort at all then u vanish 0.09

[grunter414]

[BrandonKinross]

Just wanted to point out there is a slightly easier way to multiply by 11 in your head.

Multiply by 10 and add the original number.

Or add a zero and add the original number.

Cheers!

[MsHojat]

@BrandonKinross (and everyone else) it's difficult to do (kinda impossible) with larger numbers though. The concept (not the exact method) mentioned in the video works for huge numbers — he just doesn't elaborate on how to do it with larger numbers which I'll explain in my other comment.

Using the trick of multiplication, you can do it with ANY starting numbers, like 327 and 215 — or 2-digit starting numbers (easier than 3-digit starting numbers for instance, less math work)

[az6625]

but if its 9 and 7 the seventh number will be 101

[iKiLLwCMD]

who else figured out ..... x*10 + x ?

[kd5eej]

It's easier to

X * 10 + X

[Pariahzeman]

@wondergeek7 He means add the 2nd and 3rd number in the sequence to get the 4th.

[tapatwiw]

u really math genuis



[mainllgi]

0 and 0!

0 to 0

0 to 0

NEVER 10 DIGITS

[whitespace99]

65 x 11

65 x 10 = 650

650 + 65 =715

If that's not the easiest way without a calculator idk what's wrong with you

[LUK3W4RN]

I bet he choose 4 & 9 cus they're in sf

[ladawg81]

Just do this

If it's 65*11

 65

*065

_____ 715

[oudy123]

Thats a fucked up way of multiplying by 11...... say youre multiplying 65: Add a zero, then the number you're multiplying; 715

[SFrontFrenzy]

AND THEN U VANISH

[familydude154]

Has anyone noticed that the theme song is sung by a guy with an accent?

[xnobodyspecialx]

this works if you get a double digit for instance using the numbers 9 & 6 , and going through the 7th # is 93, so you take 9 (9+3 ) 3 ......thus you get 9 12 3.............in the video brian said you cannot have a 2 digit middle portion so the 12 gets split up again the first digit gets added to the first portion of 93 = 9+1 = 10 and the second digit of 12, the 2, stays so you get 1023 as the overall total.......this works

[DaKillursFriend]

[CrewBallaz]

spanish plis!

[MrOjh378]

If you start off with 7 and 4. It didn't work I lost more than a beer.....

[Keroppix]

the proof for this is simple. Take 2 numbers, A and B, create the same 10 numbers but express them as A and B. For example, first 5 numbers would be: A, B, A+B, A+2B, 2A+3B. Notice the 7th number is 5A+8B. Now add everything, and you get a total of 55A + 88B. See how the total is always 11x the 7th value.

The trick to multiply by 11 for any size 7th num, is to take the num you are multiplying, say 9123, and perform shifted addition. 9123

+ 9123

=100353

works for any 2 positive nums

@OmarCherguiOfficial wait... are you talking about my shirt in the episode? erm... you know that's the japanese flag, right?

[pape2008]

The method to multiply any number by 11 it's the Trachtenberg System:

Ex: 9758 The result will have the following digits: 9_(9+7)_(7+5)_(5+8)_8 ==> 9_(16)_(12)_(13)_8. But 16, 12 and 13 are not digits, so the digit taking the position is only the last one (6, 2 and 3 respect.) and THEN you take the 1 from the "tens" and sum them to the digit before them. So it becomes: (9+1)_(6+1) [you also add "1" here bacause it comes from the "12" after him...AND SO ON]_(2+1)_(3)_8 => 10_7_3_3_8 = 107338

[snubbull123]

Let's say the number is XY

The sequence would be: ( X ) + ( Y ) + (X+Y) + (X+2Y) + (2X+3Y) + (3X+5Y) + (5X+8Y) + (8X+13Y) + (13X+21Y) + (21X+34Y) = 55X + 88Y = 11*(5X+8Y) = 11 times the 7th number (just check)

If the 7th number is 3 digits, do the same by considering the first two number X and the last number Y. For example 102, 10 is considered the first digit and 2 is considered the second digit. Therefore, 102*11 = 10 (10+2) 2 = 10 (12) 2 = 1122

Your can use calculator to check

OMFG he ended call on me

*cry*

[ac1th]

Yeah you could just add a zero behind the number and then add the number to that, why does brian make it complicated :D

[1297golumb]

you add 2 and 3 to get 4

[kiler2010]

to calculate any number times 11 just calculate it times 10 (add a zero...) and then add the number again IE 101 X 11 =1010+101=1111

[Reapinangel91]

Nice use of Fibonacci sequence and the 11 trick.

For anyone who doesn't know the fibonacci sequence, you best look it up. Its one of the most intriguing pieces of nature.

[iVidTutorials]

[TheLiberalSoup]

Im already a damn fucking math genius.

[ShockwaveMagic]

There is a really easier way to multiply a 2 digit number times 11 : you add a zero to the end of the number and you add the original number : E.g 23x11=230+23=253; 46x11=460+46=506.........

[Jonnay0808]

they're both only using their minds....

[TwitCentral]

Yeah im a math whiz i knew that already

[springs61204]

Love the Shiner Bock Beer out front

[Aiur89]

that was the most useless explanation on how to multiply...it's exactly the mechanics of the multiplication, anyone probably uses the same method on the paper, they just don't realize it first hand

[KalinPopov]

if the first 2 digits are 8 and 9 then 7th number is a 3-digit one

[propeng1]

No, I really wasn't going to say what is squarespace.

[lukazd99]

I just love this show

[d4m4s74]

I'm going to test if this works with multi-digit seeds. one sec

Nope, you can't

used the seeds 45 and 89

all 10 numbers in the sequence added up is 10309

the 7th number times 11 is 10307

Plus, even if it worked, it took me 30 seconds to do that multiplication in my head, so I would have lost anyway

[mothafockha]

Man This trick Get Me Laid With Asian Women

[luffy933]

I find it easier to just do it this way: (7th number = x)

x * 10 = y

y + x = answer

In a nutshell: add a 0 to the end of the 7th number, add the 7th number to the "new" number

[BlackyChan911]

THUMBS THIS UP SO EVERYONE CAN SEE:

THE NORMAL METHOD DOES NOT WORK IF THE 7TH NUMBER IS 3 DIGITS I.E 101 (THIS OCCURS WHEN THE FIRST TWO SINGLE DIGIT NUMBERS ARE HIGH)

TO FIX THIS WRITE THE FIRST AND LAST NUMBER AT BOTH ENDS, THEN ADD THE FIRST TWO DIGITS WITH THE 3RD DIGIT IN THE MIDDLE. THE LAST NUMBER THEN REPLACES THE SECOND NUMBER.

I.E

101

1 (10 +1) 1

= 1111

= (REPLACE FOURTH NUMBER WITH 2ND, IN THIS CASE IT REMAINS 1111)

THIS SHOULD WORK IF THE 7TH NUMBER IS 3 DIGITS.

[sammmmmy195]

@BlackyChan911 well this simply doesn't work. The first number I tried was 117 and it failed.

[BlackyChan911]

@sammmmmy195 damn, it worked for a few 3 digit numbers i tried. did you use to single digit numbers to begin with? with my method the 2nd number in 117 x 11 will be wrong.. but all else is correct.. im puzzled, perhaps you could try a geometric sequence haha although that defeats the purpose as it would take a while.. :)

[Evgenyiy]

@sammmmmy195

@BlackyChan911

algorithm is so simple:

XYZ*11=(X)(X+Y)(Y+Z)(Z)

QWERTY*11=(Q)(Q+W)(W+E)(E+R)(T­+Y)(Y)

so

3 digits 549*11=5 5+4 4+9 9 = 6039

[Dragoondaniel]

@BlackyChan911 but it doesnt work if its like 124 X 11 or 108 X 11

[IJoshFTW]

@BlackyChan911 It doesn't work with 8 and 9 8 9 17 26 43 69 112 - 7th 181 293 474 ----- + 1232 But 112 makes 1231 acording to your method: 1(11+2)2 1132 1231 Or did you mean like the 4th number replaces the 2nd but the 2nd doesn't replace the 4th?

[LameDestiny]

@BlackyChan911 Yup,i'm about to say that,actually it would be clearer if you wrote it this way

101

1(10+01)1

=1111

another example

348

3(34+48)8

=3828

[jwebb232]

@BlackyChan911 this doesn't seem to work with 9 and 8 ... I tried it out, and the 7th number will be 110, so it would be 1(11+0)0, which by what you said, would be 1110 > 1011, but the correct answer is 1212. Unless I misread your explanation, it doesn't work here. Please correct me if I am wrong.

[jwebb232]

@BlackyChan911 that doesn't always work ... but just multiplying by 11, or adding the number to the number x10 works, so for your example ...

101+1010=1111, and that works every time.

[jwebb232]

@BlackyChan911 I figured out the formula for the 3-digit one. you take the first and last number like normal, then in the center, add the first two and the last two numbers together. In the example, 135, you would do this:

135 = 1 (13 + 35) 5 = 1485 or, if you prefer add the first two and last two, like this: 1 (1+3) (3+5) 5 = 1485

[Gaz10t]

@BlackyChan911 9 9 18 27 45 72 117- 189 306 495 117 1(11+7)7 1277 = 1772 But 117x11=1287

[MsHojat]

@BlackyChan911 The method Brian Brushwood mentioned can be applied for larger numbers.

If the number was 1064 — start with the 4, next add 6 and 4 for the next column which is 0 (with a carried 1). Then add 0 and 6 and add the carried 1 to get 7. Then add 1 and 0 to get 1, then the final (most significant) digit is just 1 (the original most significant digit)

The rule is you just keep adding pairs of digits along the number, and carrying 1s (aside from the first and last digit)

[Linyzas]

allright i just screwd myself , i was thinking of the 10th number , not a total sum of 10 numbers... Sorry guys xD

[Linyzas]

@ryanlg1995 allright how can 8th number be the answer , i look to the show , and do same numbers and dont get ansver , please explain how they get it then

[TheLMack]

I showed this to my math teacher today. She exploded into a cloud of pencil shavings and chalk.

[Linyzas]

Same with 4 9 13 22 35 57 92 149 241 390 631 1021 Not 1012 ...

[Linyzas]

either way i am stupid or its only me getting 788 at 11:18 by manual counting 3 7 10 17 27 44 71 115 186 301 487 788? Not 781... Which makes this episode scam school useless and gay

[Armandelis]

Goddamnit! Mutliplying with 11 is easy.

X * 11 = X * 10 + X

who needs that shitty formula...

[overheersbeest]

@Armandelis it is the same, take a better look at the formula, you are doing the same thing.

[Linyzas]

@overheersbeest it is no diference if you use his formula , use armandelis one , or do mine where i add up X0 +x like if 44x11=440+44=484 ; Multiply by 11 is easy

[Armandelis]

@overheersbeest True, but I think mine is better anyways, because it is simply easier.

[addeffects]

[TheEpmagic]

lego bieber hair.

[drabikrider2323]

How about for a three digit number like if you star with 9+9 or 9+8

[ernestryles]

@drabikrider2323 for a 3 digit number its a little harder, but you put a 0 on the front and back of the number so for 357x11, you would think 03570. Then you add the neighboring numbers from right to left. 7+0 =7 5+7=12 carry the one over 3+5+1 =9 and 0+3=3 so you get 3,927

[drabikrider2323]

@ernestryles Ok thanks

[SharperThanYouThink]

what if it's the same number twice?

[musicrox127]

@SharperThanYouThink how would that change anything?

[bohemia187]

Multiplying by 11 can be easier:

For 46, add 0 to the end, making it 460 then add 46 which is 506.

This can also work with multiplying with anything really.. like multiplying 46 by a higher number like 44 u can take 6 out of 46 out n jus use 40 for now, so its 40 x 44.. u can do 40x40(1600) first then add 40,4 times (160) so 40x44=1760 then u still need to do 6x44 n add that so u can do 40x6(4x6 n add 0 so 240) n then 4x6=24 so that totals 264 so 1760+264=46x44=2024

[nathywathy93]

For 46x11

I do 46x10 + 46x1

460 + 46 => 506

Way easier and faster

A much simpler way to multiply by 11 is to just add a zero to the number (multiply by 10) and then add the original number to it for the total.
