it was because you put out the video last year.

[armeral97]

@donis1997 same but with 713 here :)

[blovesJLovesMac1]

yes, you can do that.... OR you do (the number)x1= THE NUMBER YOU PICKED!!!

prove: 7x1=7!!! 2x1=2!!3x1=3!5x1=5!

and you can go on... WORKS FOR ALL OF THEM!!!

[SuperKillster]

[alsomness]

omgggggg



[xXWhiteMXx]

description knows all

[MrM0MO]

[InfinatePunctuation]

MY BRAIN!!!!

[BD22UK]

Why is this on the front page? Things like this have been around for years, they really aren't that amazing anymore.

[THOMASHANBURY]

im really scared....i need a hug

[gibbonhunter]

just like to say this doesn't work if you are 100years old or older.

[TheRyanMode]

I'm scared!!

[BreakingBedrock]

The reason people are getting confused is because of the year bit i.e. 1991 not 91 or 1982 not 82 retry it.

[aSH0GUN]

it worked lol

[AlanosBandanos]

it worked.. what a miracle... oh no wait its just maths. still, pretty cool though.

[SamiNomSile]

Working it out without a calculator cos your a Mathematical Genius ! ;D

[rish134]

Sick guy man

[birdsofafeather1990]

I picked 5, got 521, and hey presto, I'm 21! Nice video :-)

[aidencurl]

didnt work...

[coffeemarmite123]

hey this guy is awesome and you know you can do it with any amount of digits but it cant be negative ir have a decimal

[spinballwhizzkids]

omg that was awesome :D

[Jords464]

Hey if you get 5 and add 5 and press equals, you get 10! Thumbs up if this worked!

[YamiBeast]

[MrRoach78]

lol just did it again and it worked. i thought he was saying times 10 but its times 2. very clever. dont know how ppl think of this sort of thing.

[TheLlamapoth]

That's clever :)

[moltendaniel]

i picked 7.... my birthdays in august so its already been and gone..... it cam up with 709...im 19 so what the hell... your math is flawed

[MrRoach78]

it didnt work at all, i ended up with a 4 digit number and none of them were right. i tried it 3 times

[Catisbackable]

HOLLEH FAHKIN SHIET.

[r4v1rsm]

worked for me. 719.

picked number 7 and i'm 19. :)

[EvVelocity]

[Tarantularphill1982]

it worked

[jonezy94]

anyone saying that it doesnt work, iver cant follow simple instuctions or really did need a caculator to do it.

[petipasticino]

it works, yey!

[xMusicAndRs]

Ughh, this didn't work. (I'm 115 years old)

[reaperrLoL]

@xMusicAndRs are you sure you didnt pick card number one, and you are 15 years old?

[xMusicAndRs]

@reaperrLoL It was a joke, because if i am 115 years old, then the trick wouldn't work, because it depends on your age being a two digit number...

[SharkAttackzzz]

That pretty cool

[iGzxToXiiCkZz]

worked for me :D

[JackCWelch]

@PaRaTemperHD Cool :) cheers for the praise

[rickydevil117]

oh forget my last post i just saw the times 2 comment

[JackCWelch]

@rickydevil117 No worries :) good trick though right? Everyone subscibe to me please, trying to get this account big!:D

[rickydevil117]

i took 7 and it didnt work.

7 x 10 =70

70+5 = 75

75 x 50 = 3750

my bday is 9/11/1992 so i havent had it yet so i add 1760

3750 + 1760 = 5510

5510 - 1992 =3518

if ive gone wrong then comment back

[FullOfPunk]

@rickydevil117 its not times 10 its times 2

[JammyNik12]

@rickydevil117 it's

7x2 = 14 14 + 5 = 19

19 x 50 = 950

950 + 1761 = 2711

when you was born (1996 for me)

1761 - 1996 = 715 = 7 was my card and 15 how old i am

[BigEarBembo]

that does not work at all

[Skinny004]

fucking sick bro!

[xNathan94]

HOLY SHIT :D

[MikeOxPotty]

cool

[TRIPZl]

EXPLANATION

Take 2-9 as n.

1) n x 2 = 2n

2)2n+5 = 2n+5

3)50(2n+5) = 100n+250

4)100n+250+1761 ( if this year)=100n+2011 (Notice 2011 is this year, would be 2010 if your birthday is not this year).

5)100n+2011-year of birth= 100n+age( (as current year - year of birth = age)

6) Therefore equation is 100 x card you chose, + age!

[simsohi]

@TRIPZl YOU SMART!

[WWEDivasProductionz]

@TRIPZl got it

[14sabir]

u got i wrong so hahah

[ThexLPCx]

@14sabir No dude you just did it wrong XD

The method is 100% accurate, and you can work out why with algebra.

[tomh874]

worked first time and that was interesting, well done :)

[dwarduk2]

Ah, I see how this works. Very clever :). Pity it will not work again in just a couple of months

[RedDevil2K11]

worked first time :D

[TheOwnageburst]

my age was right but not the card I choose.

[Bptips]

din'nt work

DOB 29/04/1994

i chose 8

and i got 4017 :(

[Bptips]

@Bptips argh the 1st step is times 2 i did it as times 10 it work'd XD

[dwarduk2]

@Bptips Worked for me when I put your birthday in. If you were using a calculator, maybe it doesn't use BIDMAS/PEMDAS right?

[Bptips]

@dwarduk2 ye hes says x2 at the start, at 1st i thought he said x10 XD it works now

[ThoseMacApps]

im not 212!!!

[iProRyan]

Amazing!

[8joeb]

I picked 6 times by 2 (12) than added 5 (17) times 50 (850) + 1761 (2611) - 1991 = 620 ....

[iProRyan]

@8joeb Yeah that's correct, you picked the number 6, and you're 20 years old.....

[Apterygiformes]

@JackCWelch Look at your video statistics you prat. "First embedded on pulsesubscriberdotappspotdotco­m." Obviously a website where bots can favourite your video. 100 comments, 2000 favourites. It's kind of pathetic.

[manutdman11]

sick actually worked!

[alexwelch12]

Jack, seriously how did you get top favourated video on youtube, were brothers you should tell this :P

[Jellysohcnas]

no.. didnt work... wait... it did! ah you see, i times it by ten first, but realised it's 2... :)

[Darkullx93]

Didn't work twice, I done it how i heard it the first time. Then done it how the top comment said. Both were wrong

[jammydodger123A]

lol it worked

[looweer03177]

worked!! pretty surprised

[Nozza1000]

720 :D

[Hollie5192]

Yeah, It works! Ace!

[LinkinParkKanenite]

Worked for me!

[1InchofPleasure]

Unlucky, I'm 102 years old

[JackCWelch]

@1InchofPleasure Obviously you did it wrong, you most probaly misheard me because of my shitty cold:D

[MrNoobmove]

Yep it worked, and for those that don't understand what he said, this is what you have to do.."pick a number from 2 to 9, times the number you picked by 2,press =, then add 5, then press =, then times 50 and press =and then if you had your birthday this year then add 1761 and if you have NOT had your birthday this year then add 1760 and press = then take away the year you were born in

[JackCWelch]

@MrNoobmove Thank you, was just gonna put this up on annotations :D

[MrNoobmove]

@JackCWelch No problem

[upargH]

I'm a bit suspicious of favourite botting, but at least the video was interesting. Worked for me, pretty awesome. Not sure why people can't understand you, either.

[TopmanSte]

Nice math trick! Worked perfectly for me.

422

[swiIson]

after replying a few times to understand what you were telling me to do it worked. good job

[raymondo162]

Aaaaaaaaaaah, two, not ten......... There's half an hour of my life wasted. Got there eventually

[H4ssell]

[hothead807]

It worked for me, 999 :D

[SHYBMX]

[JackCWelch]

@SuperBantersaurus Sorry, i had a cold :D

[zPINESY]

[TheOrator371]

[YoYoToTiToTiToYo]

[adambarker96]

Worked

[thejuddftw]

It said i was 15 When im 16 :o

[CoolBlokeAndABit]

I really can't figure out what you're saying from 0:53 to 1:00. Sounds like "and if you haven't had your Bafta this year...". I can assure you sir, that I am still yet to receive my Bafta for this year.

[adambarker96]

@CoolBlokeAndABit birthday....

[JackCWelch]

[jacktheehat]

Yehppp! At first I did X10 then I checked the comments :)

[eesa46]

It sounds like you said x10 at the start but he actually says x2

[EricaAndMollie]

[HANDYFAN1990]

Worked for me!
