it's not a trick.. because the real math is 24 divided by 2 and result 12. if you think of a number you will extract it anyway in the end, and when you double your number you divide by 2 after the next step. it's not a trick, just simple math.
@ghostrider1718 No, you and I know it isn't a trick, but please remember the audience this is aimed at. A 13 or 14 year old grade 8 student just learning algebra thinks this is "magic", I know, I've done on many classes over the last 41 years of teaching (1970 - 2011). Then, when you show them why it works, they get a bit of a different feeling about algebra. A lot of math "tricks" have algebra behind why they work.

@minkusbc If you are more advanced in your country, then that is great, try this one: Think of a number, square it and multiply by 5. Now subtract 3 times your original number multiplied by one more than your original number. Now subtract 4 times 3 less than half of your original number squared. What do you end up with?
@whooguy45 Wow, i whooguy45 ever clever! Try commenting on the video, and bringing profanity in. Then maybe some schools will reverse their ban on youtube so that students who can benefit from math videos might be able to watch them!
how did you know that my number was twelve??? oh because there is a subliminal message 24 divide by 2. when you said - think of any number.
actually i dont like those math tricks where one step is ''do something with your number'' because that reveals the trick. if you say - think of any number , divide by that, multiply by that, and so on BUT only without the ''do that with your number'' then i would be amazed.
@gassybagmike Sorry, but it does work, you forgot to start off by doubling 2112 to get 4224, THEN add 24 to get 4248. Now divide by 2 to get 2124, and subtract your original number of 2112 to get 12! Math rules !!!
Double 5, you get 10 (not 25). Add 24 you are now at 34. Divide by 2, you are now at 17. Subtract your original number of 5 and you end up with 12 !! It works for ALL numbers even negative π or the square root of 45,378.987.
It works with ANY number. You doing your math wrong, is not this guy's problem. I explain like he said... If you have 5 and double it you get 10, then you add 24 and get 34, then you divide by two and get 17, subtract the original 5 and you get... 12! (2*5+24)/2-n This guy is right.
@Banghouse : I'm not sure who you are referring to with your comment "you are a dummy." However, it's not cool, when somebody is trying to learn, to call them that. If it is aimed at me, the writer, then it really is a weird statement to make.
no i was not talking about what is in the video... i was replying to waxers84's comment... i wish youtube returns the thing that makes you beable to tell if someone is replying or not...
Well im in year 8 in my school and i'd have figured it out fairly fast we are doing about rules and stuff like this a the moment, pretty cool trick hought i'll try fool some of my less smarter friends :P
That's right. But this is aimed at BEGINNING ALGEBRA students, grade 8 or grade 9. The "trick" is not really the big thing, the PROOF of why the trick works is what is important. By the way, try this with 30 grade 8 students in a class, where they all think of different numbers. Then they do a bunch of things to them, and they all "magically" end up with the same answer!! It's priceless.
first you have a number like 2 then you double it makes 4 if you add 24 you will get 28 but then after dividing it by 2 again you just substract your own number which was 2 and then you get 12. If you Look at it the only thing you're doing is getting DISTRACTED by al the numbers. so you substract your own number without noticing it. now do the same as in the vid but then add 13 instead of 24. you'll see you'll ALWAYS get 6,5 use 66 you will get 33 use 34566 you will get 17283 Just Try.
It doesn't have to be 24, it could be any number, although even numbers are a bit easier. If I added 36, the result would be 36 divided by 2 or 18. If you changed the trick to tripling a number and adding 36 and then dividing by three, the result would be 36 divided by 3 or 12.
Does to!!! Double 11 and get 22. Add 24 and get 46. Divide by 2 and get 23. Subtract your original number (which was 11) and you get 12. (23 - 11 = 12).
That's pretty freaking cool. Yeah.. I guess the doubling it is squaring it which automatically makes it even. Adding 24 automatically makes it a particular prime number which can be factored down to 12. Very interesting.
Remember the audience this is aimed at. When you have 25 kids all trying different numbers and they all come up with the answer 12, they are amazed. Then, since algebra is new to them, you can show them how it works, and that helps them understand that algebra can do some neat things for them. No, the trick isn't earth-shattering, but for beginners in algebra, it is neat!
Actually it works with ANY number, positive, negative, rational, irrational, even complex! Let's take - 12. Double it, you get the result - 24. Add 24, you get 0. Divide by 2, you still get 0. Now subtract your original number and here you subtract a negative! So 0 - (-12) = +12, the answer predicted! Try - 13, double it, you get the result - 26. Add 24, you get - 2. Divide by 2, you get - 1. Now subtract your original number and here you subtract a negative!
thats cool but its just math because you tell us to subtract the number we were thinking so u cud make the answer equal 1362696 if u wanted it to. and it wouldn't work with negatives
Yes, it will work with any number rational or irrational. Let's try a negative number like - 2. Double it, you get - 4. Add 24, you get 20. Divide by 2 you get 10. Subtract your original number you get 10 - (- 2) = 12 ! Remember, subtracting a negative is just adding.
I stopped the video right now before posting this. It makes sense. (my explanation before hearing yours) You have your number then its doubled. then you work backwards. number appears, double, halved, disappears. then all you have left is 24/2 which will always = 12. This trick seems familiar....when i was little yeah....it makes a whole lot of sense being in algebra last year, geometry now
If you're now in Geometry, you may be interested i a series of videos on constructions with compass and straight edge that I am putting up this week. I show how to do it, and, through Geometry "proofs", show why they work. Cheers...
XD on no. thank you. I just finished Geometry. In fact My geometry finals were today. The only issue I had was with sine cosine and tangent...very disorientating...
I can't win... Sorry that I "killed it with your math and n's", but with all my tricks and shortcuts, I want to explain why it works as well as how to do it.
As I have said before, the trick is only part of this, and it is a very simple trick aimed at people who are relatively new to algebra. The important part of this is in the "proof". For the first time, a student may begin to see HOW things work. This is huge step in intellectual development. Certainly, swearing and name calling, is not the way to react. Try to think of how you can take this further. Remeber, it is better to be thought of as ignorant, than to open your mouth and remove all doubt!
ok im twenty five and i thought that was a really great trick i love it thank you for posting it i truly appreciate it. as for these jerks don't mind them they really are ignorant people who choose to do nothing but be negative, i guess thats how unhappy they are! thanks again
Apology accepted. Algebra proves why the result happens. If you don't think that it is a trick, then try it, as I have done dozens of times, with a class of 30 grade 8's or 9's. They all think of different numbers, do a bunch of things to these different numbers, and all end up with the same answer!! The look on their faces - priceless!
First of all, your comment does not make sense. Secondly, your last two words have no business being in a comment about mathematics and the joy it can bring to people.
I just want to say man, you've really helped me in my Algebra class. You're practically a lesson that I can watch and review over and over again. I've gone from a 74 to a 93 in my Algebra class, thanks to you man.
I'm not sure what you are getting at here by saying "u fail..". You have changed the trick by adding 20, not 24. Your math is correct, and if you add 20, you will end up with 10, no matter what number you start with.
what?!?!? it could only ever be twelve! I appreciate bringing maths on to Youtube. but by eradicating previous parts of the sum completely you'll end up with the original. I don't believe the word 'trick' applies here. sorry
Again, as in other comments, the "magic" here is not in a very simple trick, but in the proof about why it works. This opens up a whole new world for students who are new to algebra. It allows them to open up that beautiful door labeled "proof".
Again, I must emphasize this works for all numbers, fractions, negatives, decimals even irrational numbers. Try it with the square root of 2! Now, the trick, I know, is not spectacular, but the proof of why it works is what I was aiming at for people new to algebra.
Though somehow it just made me realize that all those years I spent learning algebra in high school were meaningless; this is the first time I've seen a variable equation since graduating six years ago.
so lame... it's like saying "alright, pick a number... now subtract that number and you get 0!" the only difference is they add in a few operations to make it look fancy lol.
Just remember, the audience for this video includes a lot of people that are new to algebra. The "meat" of this video is not the trick, but the proof of why it works. For beginners to really see how algebra can answer why something works, is powerful.
everyone think of a number between 1-1 million. Double your numbers. Add 360. Now half your numbers. Now take away the number you got with your original number. answer = 180
The solution is simple. you think of a number, then double it, then add 24. then you undo the add 24 by dividing by 2 and then you undo the doubling by subtracting the original number, thus the answer is always 12. If you plug in another number other than 12, the number will always be half of the one you have chosen.
Let's see, 36 doubled is 72. Add 24, you get 96. Divide by 2, you get 48. Now subtract your original number of 36 and you get 12!!! This trick will work with any number, fractions, decimals, radicals, irrationals etc.
My number was 3. I was amazed with the trick when I heard you call 12 out. Thanks for the trick. All of your viedos are cool, especially for someone like me who is taking college algebra online.
Oh my fucking god, thats sooo lame. I did that liek in first grade and i still laughed about it, but it just proofs the lack of education in some countries...
please do not give away the best thing about the trick... If you don't know what im talking about, i mean that i can do this with multiple people, and guess their numbers even though they would all be different numbers.
it's not a trick.. because the real math is 24 divided by 2 and result 12. if you think of a number you will extract it anyway in the end, and when you double your number you divide by 2 after the next step. it's not a trick, just simple math.

sadly, it is. not me personally, but 80% of people in my class would probably be amazed at this.
since you double your number to add 24, when halving again, it's your number + 12 more. subtract your number, and you've got 12 left.
it's kinda sad that kids my age can't use logic that far by themselves... -_-;

XD on no. thank you. I just finished Geometry. In fact My geometry finals were today. The only issue I had was with sine cosine and tangent...very disorientating...

I can't win... Sorry that I "killed it with your math and n's", but with all my tricks and shortcuts, I want to explain why it works as well as how to do it.

veryyyyy stupid 24/2 will be ALWAYS equal to 12 you stupid asshole.. wasted my time

As I have said before, the trick is only part of this, and it is a very simple trick aimed at people who are relatively new to algebra. The important part of this is in the "proof". For the first time, a student may begin to see HOW things work. This is huge step in intellectual development. Certainly, swearing and name calling, is not the way to react. Try to think of how you can take this further. Remeber, it is better to be thought of as ignorant, than to open your mouth and remove all doubt!

ok im twenty five and i thought that was a really great trick i love it thank you for posting it i truly appreciate it. as for these jerks don't mind them they really are ignorant people who choose to do nothing but be negative, i guess thats how unhappy they are! thanks again

i am sorry if i offended you... but this has nothing to do with algebra. and it is not a trick as well! sorry again...
khaledshawky 2 years ago
Apology accepted. Algebra proves why the result happens. If you don't think that it is a trick, then try it, as I have done dozens of times, with a class of 30 grade 8's or 9's. They all think of different numbers, do a bunch of things to these different numbers, and all end up with the same answer!! The look on their faces - priceless!

I just want to say man, you've really helped me in my Algebra class. You're practically a lesson that I can watch and review over and over again. I've gone from a 74 to a 93 in my Algebra class, thanks to you man.

I'm not sure what you are getting at here by saying "u fail..". You have changed the trick by adding 20, not 24. Your math is correct, and if you add 20, you will end up with 10, no matter what number you start with.

you do division different then i learned you also do a different version of that trick. but yah good job explaining it.

what?!?!? it could only ever be twelve! I appreciate bringing maths on to Youtube. but by eradicating previous parts of the sum completely you'll end up with the original. I don't believe the word 'trick' applies here. sorry
WhispGore 3 years ago
Again, as in other comments, the "magic" here is not in a very simple trick, but in the proof about why it works. This opens up a whole new world for students who are new to algebra. It allows them to open up that beautiful door labeled "proof".
minkusbc 3 years ago
soo cool that i subscribed :)
fake2k1337 3 years ago
anyway,
1.pick a number from 1 - 10
2.double it
3.add 20
4.divide by 2
5.subtract original
your answer will ALWAYS be ten. lol, nothing impressive. just boredom talking.....
lilken96 3 years ago
Just remember, the idea of this trick is that we can prove why it works. From that starting point, one can then make up there own tricks and proofs.
minkusbc 3 years ago
why doesn't it work with 2, 3, and so on...??
lilken96 3 years ago
It will work with any number, rational, irrational, imaginary, positive, negative etc.
minkusbc 3 years ago
smiling face in algebra ('',) is easy
143888anne 3 years ago
Pick any integer between 11 and 13, but it cannot be one of those. Ok now double it. Then divide by 2. Your answer is twelve!!!
konzwambii 3 years ago
Again, I must emphasize this works for all numbers, fractions, negatives, decimals even irrational numbers. Try it with the square root of 2! Now, the trick, I know, is not spectacular, but the proof of why it works is what I was aiming at for people new to algebra.
minkusbc 3 years ago

Though somehow it just made me realize that all those years I spent learning algebra in high school were meaningless; this is the first time I've seen a variable equation since graduating six years ago.

so lame... it's like saying "alright, pick a number... now subtract that number and you get 0!" the only difference is they add in a few operations to make it look fancy lol.

Just remember, the audience for this video includes a lot of people that are new to algebra. The "meat" of this video is not the trick, but the proof of why it works. For beginners to really see how algebra can answer why something works, is powerful.

everyone think of a number between 1-1 million. Double your numbers. Add 360. Now half your numbers. Now take away the number you got with your original number. answer = 180
fresher1998 3 years ago
The solution is simple. you think of a number, then double it, then add 24. then you undo the add 24 by dividing by 2 and then you undo the doubling by subtracting the original number, thus the answer is always 12. If you plug in another number other than 12, the number will always be half of the one you have chosen.

proven wrong, i used the # 36, and the answer was 4! unless the #'s have to be 1-10?
Zeoncooper 4 years ago
Let's see, 36 doubled is 72. Add 24, you get 96. Divide by 2, you get 48. Now subtract your original number of 36 and you get 12!!! This trick will work with any number, fractions, decimals, radicals, irrationals etc.
minkusbc 4 years ago
thanks, proven wrong!!!
Zeoncooper 3 years ago
My number was 3. I was amazed with the trick when I heard you call 12 out. Thanks for the trick. All of your viedos are cool, especially for someone like me who is taking college algebra online.
Thanks
jazzybronze07 4 years ago
Double 11 and get 22. add 24 and get 46. Divide by 2, you get 23. Subtract original number (which was 11) and you get 12. Voila!!
