A Math "I can read your mind" Magic Trick

[FelixRevealed]

cool trick don't listen to these morons they don't understand logic obviously.

[teica226]

awesome!

[josheball159753]

i can read your life( you have no friends no life and your a virgan) ding ding ding CORRECT!!!!

[minkusbc]

@josheball159753 Wow, it must be neat to be such a positive guy!! Of course you should check on your spelling if you want any educated person to take you seriously. Also, comment on the video instead of spending time dragging people down,

[josheball159753]

@minkusbc cool............ at least i dont live in my moms basement

[MultiSuperBoy9]

MrVarken123 exactly beotch and I know I spellt it wrong on preposterou

[MrVarken123]

no ..sir you math magic is not rigth bec.

4217+5386+4613+6937+3002=24115 try to sovle it again sir..!!!!

[minkusbc]

@MrVarken123 Sorry, but my numbers are correct, you copied them down wrong. They should be 4217 + 5386 + 4613 + 6937 + 3062 which equals 24215 just as the video says. By the way changing the last number to 3002 would make the sum 60 less which is 24155 not the 24115 that you have.

[VideoAbduction411]

FIXED!!! 

[qnoobcakep]

its easy lol ;p u just put numbers in ur numbers u really fast do the math in your head ;p than u add ur number

[alman021]

Thank you very much

[rodocruzr]

also just as a side comment, it was funny to show my friends cuz at the end they all were sayin that i was just adding all the numbers up as we went in my head and that the numbers i gave were just big number hoping that whatever they gave my wouldn't go beyond the number i wrote onthe paper. i just told them that if they wantd to think i was some sorta genius that could pull off something like that then fine by me xD

[rodocruzr]

just one question, i really like the trick andi hve shown it to some friends and family, however as i was showing the trick to my friends i found myself breacking my own rules, and what i mean is that i said that the number had to be between 1000 and 8000 and they were giving me like 1450, problem is i would have to write 8549 which is in fact larger then 8000 and thus breacking my own rule. how would you say i couldimprove upon the trick to prevent this from happening? make it 2000 to 8000?

[thekas1997]

i think it is rehearsed.

[maswwww]

thumbs up if you sall him touch the paper after saying he wont:))

I used to do this trick all the time, except i did it with 5 digit numbers :)

[TheGolemlord]

math is my favorite science...

[missyxxxsorted]

cool im gonna practise that and use it on my friends and family!

[browneye1968]

Whoa! This is what i call an awesome math trick

[Fetey2]

This is awsome!!!!

[xKingPola3ux]

hey man, ignore these losers, i think this was pretty fun and cool. These kids are just really immature.

nice job :)

[TheZombiedk]

[beaniegirl345]

Hello!

A couple of us at college are working on a math project that involves a variety of math tricks. A couple of your videos are exactly what we need and we were wondering if we could get in further contact with you in order to clarify a couple of things. Please post back to my wall in order to let me know if this is possible.

Thank You!

[minkusbc]

@beaniegirl345 Sure, beaniegirl345! Drop me a line and tell me what's up. My personal email is wloutet@shaw.ca

[MrKINGofRING]

very nice sir

[nightmare4034]

lol we learnt this trict on 6th grade... literally...

[nirvenesh20]

its totally cool....i love it..hope u can show us more of maths trick please update me

[garahehe]

thats not bad atall, my maths teacher did it to me but with 6729 as the resultant number to make it more difficult, i missed it :( but yea fair shout cos i missed it again :(

[MissAnthropy1349]

I was thinking of this trick today, but couldn't remember how it went. Thanks for uploading this vid!

[mynameischaro]

really cool! i'll use it in my class. thanks :)

[mimi132ful]

that's a cool trick :D

[Justcallm3god]

i thought it was kinda cool too.

[minkusbc]

@walapeogunit111 Wow! Your intelligence really is showing through. Comments on the content of the video are more than welcome. Swearing and name-calling is really over the top. We try to make these videos to help students learn and have fun with Math. Your type of comments cause school boards all over the world to ban YouTube from the classrooms!! Once more, stupidity does its thing...

[garahehe]

@walapeogunit111 dude grow up

[queensugar10]

u made this on my birthday xx

[aannttee11]

I like this trick! Good job minkusbc!

[amf00234]

cool

[Haelstrome]

This is a cool little trick, but I figured out what you did when you wrote the first number, but I try to be analytic like that when there's a 'magic trick'.

I could really see it impressing children, but frankly, a grade 12 class should not be impressed by this trick. Grade 8 I might see, but I don't mean to offend anyone but that sounds like a stupid grade 12 class.

Maybe I'm just being too critical, as I just had my Calculus exam, but I don't see it fooling a grade 12 class.

[minkusbc]

@Haelstrome : Yes, I have shown it to Grade 12 classes and my very good Advanced Placement Calculus class. You couldn't have figured out what I did after I had written the first number, because you didn't know what I was going to do. I think that you are being to critical, maybe it is the way you deliver the "magic" that makes it cool. Try it on a few people, see what happens. Just make sure no digits are repeated or in an obvious patter. Have fun, you're allowed to!

[meghanorlando]

i really think you guys should leave this guy alone. he took the time to make this video and all you guys are doing is making him feel bad. i thought the trick was really cool.. great job!

[minkusbc]

@meghanorlando. Thanks, for the pat on the back. Some people are way too critical of what is really a simple little trick.

[wizkidsid1991]

@minkusbc

clearly well thought out

[Balaman4]

is it your own idea? if its not still great :)

[eviltube1111]

reniffer is a big mean poopoo head

this video was entertaining.

[cucngu66]

it's a bit confusing, why did u add 20000?can we add aother number,like 30000???

[minkusbc]

@cucngu66. If you had 3 sets of numbers that added up to 9999 then you would subtract 3 and add 30000 by putting a "3" in front.

[DjSwayne]

hello newman

[DjFiZzZle]

1. copy and paste

2. send this to 2 other videos.

3. hold your breath for 10 seconds.

4. press refresh twice.

3. LOOK AT YOUR HAND

[ratmkinojake]

8-5+3=6

[ratmkinojake]

4+2+1=7 thats a pattern

[Wavenet08]

Yaaaaaaaaaaaaaaaayyyyyyyyyyyy !!!!!!!!!!!!!!

[maahiy2k]

it was simple but, the simpler it gets the more bril;liant it is!!!

[oli90]

I paused it after the trick and eventually figured it out, but i must admit I was definitely wowed at first.

I'll be sure to pull this on someone lol.

[HappyLappyNappy]

woah

[harismokhtar]

ahaha..its not even a trick at all.evry1 knows how he did it

[minkusbc]

If you went to the end of the video, or if you were the one in a hundred who observes the pattern of 9999 as the trick is unfolding.

[wertyou567]

woah

[90f94]

this is what my teacher did

[MasterMedit]

easy ... The first numbers are just a number. from there you know the answer.

because each number you add up to 9 and so the answer remains the same.

For example:

9999

1111

You do

8888

the answer is 19,998

anyone can: P

[minkusbc]

Yup, if you go to the end of the video you see that explanation.

[MasterMedit]

xd :D

[bigt56560]

EVERY ONE THE ANXWER IS X/2 ok its simple math i mean cmon pppl!

[minkusbc]

What question are you looking at? Again, every time I do this in front of a class, I have kids who are amazed.

[DarigonKogi]

I could see what the writing was - didn't know what was it for lol. o-o''

[93saul]

i saw that right away show me something that will get me

[minkusbc]

Congratulations! I have done this trick 100 times in front of classes, and no one has *seen that right away". Consider your self, very observant!

[rbairos1]

Fun trick!

[minkusbc]

No, I don't need to do anything like that. I have done this trick in front of classes for about 30 years, and never needed to do anything but subtract 2 from the original number and place a "2" in front of that result.

[rennifer691]

i dont see how amazing this is.. you added your own numbers so thus forth making this really dumb

[minkusbc]

Yes, I added my own numbers, but in real time, each number I added within abut 10 seconds. If I knew the answer and was doing all the work in my head, I would be a genius at mental math. I have done this trick in front of classes of up to 30 students from grades 9 to 12 over 20 years, and NOT ONCE have they failed to be amazed, because I put my numbers down so fast that I could not possibly be doing it in my head. Watch to the end of the video to see how I get my answers so quickly.

[rennifer691]

umm. no it doesnt take a genius to make numbers equal nine. that isnt hard. or does it take a genous to add 20000 and then subtract 2. really a 5th grader could do that math in ten seconds

[minkusbc]

You're right, a fifth grader can do this trick AND wow his parents and classmates.  I have shown this trick to hundreds of classes from grade 8 to grade 12, and they all are impressed. None have got the "trick" until it is explained to them. Try it. Now, if you make sure there are no repeating numbers and no pattern to the 4 digits, it is harder to pick out the solution.

[rennifer691]

ok now you just conrtidicted yourself which tells me you really dont know what you are talking about.. and when you keep repeating the line "i have shown this trick to hundreds of classes from 8th to 12th grade" really doesnt say much either. any one can be "impressed" by a simple "trick". and you cant reall tell me that EVERY SINGLE student you have shown this to has been impressed since i am a student and wasnt impressed in the slightess

[minkusbc]

Don't be ridiculous, of course I cannot say "every" student was impressed. I did say that all the classes were impressed. Each class' reaction was one of disbelief, followed by "how'd you do that!". I then showed them the trick, explained how to tell others, and told them to pass it on. I'm sorry that I did not impress you, but then it's hard to impress someone so critical. Have a lovely life....

[rennifer691]

no matter what kind of trick you do you are going to get the response of "how'd you do that!". now i am very easy to impress but not with manipulated math tricks. thank you i will have a lovely life.

[dimflamingo]

@rennifer691 Don't be a dickhead. He's just trying to show a maths trick which for many will evoke a positive response. Are you trying to prove you're cleverer than him? What difference would it make? You're just being awkward.

[rennifer691]

@dimflamingo no i wasnt trying to prove i was "cleverer" then him. i was just stating my opion and then defending it. and for the record being called awkward is deffeintly a plus as far as im concerned. so thanks for the compliment

[ozzyfalco108]

pick a number

add 5

subtract 8

add 20

subtract the number u choose

subtract 3

and ur answer is 14

[jamil381]

how do you do that

[rbairos1]

The number you pick in the beginning is always subtracted later in the second last step, so whats left is: +5 -8 +20 -3

or 14.

[Stasy00]

cool

[dathugfamily]

wow, that was an awesome trick :)

[joanne4lothiann]

thats cool

[earthblast23]

id u pay attention to the back of the paper that he is writing on, u can tell he doesnt write a 2, but its there

[liamthefish1]

cool

[FirestarLeader1]

I got 6 error. I started with 8000 anyway great vid

[Error081688]

Pick a number, any number

Double it

Add 12

Divide by 2

Subtract the number you started with

Add 4

Divide by 2

Your answer is 5.

:) simple algebra.

[naruto4lyf1997]

lmao i got nen so u = fail i got my dad to double check just incase i did the mental math wrong but nope

[Error081688]

what did you start with?

[bigt56560]

yes, it is very simple. solution = x divided by 2.

[Error081688]

you got it. well, x / 2 and then whatever steps I decide to add after it. The point being that the final answer has nothing to do with the original number chosen by the spectator

[TyYann]

I always loved that trick and always got a great response from the kids in class.

[thekilmer09]

how does it work ????? ( our speaker is not working , I could not hear anything )

[sepohnekorb]

hahah i learn this trick 1year ago XD...

[sepohnekorb]

hayzzzz this trick is noob...hijacker17758 is right...

if he ask you to give him 4digits then he will right 4 digits that will equal to 9...

[minkusbc]

If you saw this without watching to the end of the video, then you are very observant (and I congratulate you). I have done this trick about 25 times in front of classes, and I have never had anyone observe that without being told. Well done.

[mazaza400]

c00l_

[hijacker17758]

from 0:48 u can already tell what numbers he was writing...

[cinsepehri]

Wait my coculator doesn't do math. Should I get a new one?

[minkusbc]

I know I shouldn't have made fun of the person's spelling, but I couldn't resist. Now maybe we could figure out that if a coculator did exist, what would it look like? Maybe a calculator shaped chocolate bar?

[clownslider]

learn your math the correct awnser is 24515 and i used a coculator

[minkusbc]

I'm sorry, but you are wrong. The correct answer is the one stated in the video, namely 24215. Please check it again, this time with a calculator, not a coculator.

[FENiXRiZN1]

LOL nice one XD!!

[Jules787B]

omg lol coculator wtf is that

[eugene215111]

i been knew how it works from my friend from 4th grade :D

[Jamonmyguitar]

I got taught this trick at school, its really easy.

[dmc4khff]

duhh i figured it out when you put your own number in

[minkusbc]

You are very observant then. I have done this trick in front of classes for over 30 years, and have never had a student notice that.

[nathands007]

AWSOME!! :D

[lorenzog619]

cool trick! :D

[TeamXBlackOut2]

boring

[minkusbc]

I decided long ago that that word would not be part of my vocabulary, instead, I would look for knew knowledge and patterns instead. Try this trick with a class full of grade 9's or even grade 12's as I have, and you find it anything but the word that you have used. I'll really try harder to entertain you next time!

[VitalSigns1]

Whoa...that was actually a pretty cool video for once

[fire8675309]

that was REALLY cool. but im not so good at math so idk if i could do that so easily :P

[yajD11]

wew,there are peoples in your front and show the numbers that you are write.damn

[minkusbc]

No, if you did this trick in front of a class, as I have done, then people would see that. Watch to the end of the video and you will see how I actually do the trick

[dannyjar100]

great

[Stonebr1dge]

really cool trick!

[scarcio69]

yes lima 4000 and that's y the numbers have to be under 8000, because if they were grater than the answer could be grater than 2400

[minkusbc]

Actually the numbers can be anything under 10,000. However, if they choose a number such as 9,538 I would have to reply with 0,461 in order for the two to have a sum of 9,999. This seems a bit weird for a four digit number to start with a "0", so I try to get people to choose numbers less than 9,000 so this does not come up.

[stickmaster546]

that's pretty cool

[Liam40000]

It doesn't matter what they say. As long as he gets to add the last number he can add it into the written down answer.

[minkusbc]

Most people (including myself), could not figure out the result that way, in their head, that quickly. Watch to the end of the video to see how I do it.

[zuhizu11]

great trick man ima try that on my siblings today see what they say

[cyrok215]

thats an awesome trick!

[m123bl]

AFGUNZunited is quiet stupid, and the same for fang605. That trick is amazing, and it's nothing wrong with either the trick nor the audience.

[AkshXP]

awesome trick! :D

[AFGUNZunited]

omg, this guy got all of good. listen yea

After he got the first number from the audience, he added it to 1998 (9999+9999) which gave him the secret number.

Then he got a number from the audience and then he said a number which both of them add up to 9999

He did this step again which adds up to 9999.

adding them both up gives 1998+first number gives the hidden number.

Omg this guy really got all of you.. tut tut tut.

You are a good maths person but this aint an "i can read your mind" trick

[AkshXP]

you're a dumbass LOL!

why don't you actually try doing the trick yourself.

i don't even get what u said. do the trick!

good luck champ :)

[jredohyeah]

its not hard at all

[AFGUNZunited]

why doesnt he make the fake "audience" to say the last number... or get some REAL audience to say the LAST number. I used to do these when i was 14

[minkusbc]

Again, I am a Math teacher. The trick works through algebra, not any "fake audience". The three people who helped me out here had never seen the trick before. They were 11, 13 and 57 and were all quite surprised, so the sound track is real.

[AFGUNZunited]

lol omg are u lot dumb or what, that is the most stupid trrick ever. the man is either a good mathematicion or the "audience" were fake.

the last number, the guy said 3062. he quickly added up the other numbers and subracted it from 24215. As i said, he is either a good maths person or the "audience" is fake.

btw how can all of u lot fall for that?

[fang605]

Hahahahaha your right

dumb pple man

they fall for anything

[minkusbc]

Did you not watch the end of the movie, where I explained how I did it?

[minkusbc]

The guy who made this videos grandaughter : hi, I was in the audience when my grandpa did this trick, and it was not fake. I'm 14, and quite enjoy math, and my grampa happens to be a high school math teacher and is very smart! so watch what you say! :)

[tyytan]

ahh thats pretty gd

always wondered how people do that

[NokiGP]

Thats geat :) I really love all of your videos :) your awesome :)

[ragtimest]

wow~!

[laBoricuaReina]

that was great! i llove your videos you are realy realy helpful!!

[acecf23]

Good to have you back!

[amatrineprincess77]

LOL always wondered how that worked! ;)

[DotxxHackxxSword]

lol at the end.

- eh...

[MELIPAISITA]

awesomeeee 5 stars :)

[Amouse100]

cool

nice trick :)

[TheOldJericho]

Nice trick, but the audio is too low

[stonedslacker]

lol the girl in the background. wow... yeah... Haha she sounds stunned

[ghorse147]

you da man

[cptobvious64]

Great video, this is a very clever and unexpected math trick. Your videos are fantastic. I will be looking back on some of your earlier work on factoring for an upcoming exam. You've taught many people a lot of math. Thanks
