Amazing Human Numbers ( Too Good)

um…ok. so?
wtf this is not magical at all? this is multiplying/adding sequences of numbers by arbitrary numbers and then adding numbers relative to the first sequence… wtf this is so stupid! there is nothing special about this.
this is a much more special relationship
adding prime numbers in sequence begins to generates exponents of 2,
1 = 1 = (2^1)
1 + 3 = 4 = (2^2)
1 + 3 + 5 = 8 = (2^3)
1 + 3 + 5 + 7 = 16 (2^4)
next this goes to 3^3, but then im not sure what relationship they have. However, this is a much stranger relationship found in numbers compared to “some # * some # + some # = WOW!”

Cool.
ascii kids got you beat…
You have waaaaaaaay too much time on your hands…
Regarding the last example (with all the 1’s):
15 years ago (i remember very well, it was in 1991) I noticed (and tried to prove) that all the palindrome numbers with an even number of characters, can be divided by 11. On top of that if the first part of the number is in ascending order (like 1991 , 123321, 15789998751 … ), if you divide by 11, the result is palindrome as well. Check it out.
second can be extended to:
12345679 * 9 = 111111111 (9*1)
12345679 * 18 = 222222222 (9*2)
12345679 * 27 = 333333333 (9*3)
12345679 * 36 = 444444444 (9*4)
12345679 * 45 = 555555555 (9*5)
12345679 * 54 = 666666666 (9*6)
12345679 * 63 = 777777777 (9*7)
12345679 * 72 = 888888888 (9*8)
12345679 * 81 = 999999999 (9*9)

You forgot a classic Mathemagical number 9.
9 x 1 = 9 | 9 + 0 = 0
9 x 2 = 18 | 1 + 8 = 9
9 x 3 = 27 | 2 + 7 = 9
9 x 4 = 36 | 3 + 6 = 9
9 x 5 = 45 | 4 + 5 = 9
9 x 6 = 54 | 5 + 4 = 9
9 x 7 = 63 | 6 + 3 = 9
9 x 8 = 72 | 7 + 2 = 9
9 x 9 = 81 | 8 + 1 = 9
9 x 10 = 90 | 9 + 0 = 9
It’s like, Magic!
Err, correct 9 x 1 = 9 | 9 + 0 = 9… misclick.

That was awesome..thanks for the post..
Take a calculator (not calc.exe from windows), turn upside down, and calculate th following phrase: LOL (707) times LOL makes…
Yeah, that is great. I was great in maths at school, and yes, I know why *g*
COOL! just made my day… now am going to waste more time playing with my calculator…. 80087355
I’ve seen this before. There are hundreds of other brilliant mathematical things, you should list some stuff more than multiplication.
Read Goden Escher Bach – Eternal Golden Braid (I forgot the author, but read it)
ps. you’ve been dugg!! nonstopmasti? indian site. neat.
The book you’re referring to is: Godel, Escher, Bach: An Eternal Golden Braid by Douglas R. Hofstadter.
I can’t believe that this ‘mathemagical’ page was ever dugg so high. I’m losing faith in peoples power to digg sensibly. Surely this has got to have been manipulated up the rankings?
Lame…
yeah, i’m with nate on this one. wtf is the big deal? of course there’s gonna be symmetry within math problems. there’s symmetry everywhere we look. we just don’t see it all the time.
well, thats lame … there are much better things with more insight. let’s have a look at the powers of 11:
11^0 = 1
11^1 = 1 1
11^2 = 1 2 1
11^3 = 1 3 3 1
11^4 = 1 4 6 4 1
…the pascal tringle … and to avoid carring the 10th digit to the next number, think in an infinite base…
w00t!?
mareks :
It’s been a while since I’ve studied math, but it looks like there are some problems with your example:
>> adding prime numbers in sequence begins to generates exponents of 2,
>> 1 = 1 = (2^1)
1 is equal to 2^0 or better yet, 1^2
>> 1 + 3 = 4 = (2^2)
>> 1 + 3 + 5 = 8 = (2^3)
1 + 3 + 5 is not 8, it is 9, which is 3^2 not 2^3
>> 1 + 3 + 5 + 7 = 16 (2^4)
maybe this could be 4^2 ??
I’m seeing a pattern here…
so
1 = 1^2
1 + 3 = 4 = 2^2
1 + 3 + 5 = 9 = 3^2
1 + 3 + 5 + 7 = 16 = 4^2
1 + 3 + 5 + 7 + 9 = 25 = 5^2
1 + 3 + 5 + 7 + 9 + 11 = 36 = 6^2
1 + 3 + 5 + 7 + 9 + 11 + 13 = 49 = 7^2
cool…
[...] Mathemagic is a collection of nifty mathematical oddities. [...]
mareks: 2^1 = 2, not 1; and 1 + 3 + 5 = 9, not 8. Your attempt to produce a more “magical” sequence is woeful. You will find no geomatric or algebraic pattern amonsgt primes or their sums. The only relation easily rendered is that lim n-> (infinity) of p(n) (the number of primes less than n) /n = ln n.
digdug: 9 is not prime–you are adding odds, not primes. Yes, the sum of odds tields squares. This can be observed in the following seqience of picturres:
*
* + ** = **
* **
* + ** + *** = ***
* * ***
* ***
and so on . . .
Well, my little “L”’s and squares don’t display as they did on the composition box . . . but look at an n x n square and you will see it consists of concentric L’s which consist of consecutive odd numbers.

@ 31 and 3
2 is also a prime number, so you are both off!

I like how you leave out the next step:

Andrew – of course “1 + 3 + 5 + 7 + 9 + 11 + 13 + 17 = 66 = 8^NOTHING!!!”
Because as was pointed out, had you been reading the comments, this guy was adding odds, not primes. Or did you miss that he had “9″ in there?
Therefore, even though he isnt adding primes like he thought, if you add odds, the next step is:
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64 = 8^2
Next time, read the comments and think.
@38
Andrew, the CORRECT next step would be:
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64 = 8^2

1 is not a prime number either, which kind of screws everything up there, huh?
(1 has only one factor, primes have two, 1 and the prime)
All you smart math people suck!! The only thing worse than a stupid jock is a smart idiot that is never wrong!! Why are you stupid ’smart’ people flaming each other in the comments section? How pathetic are you? IT’S THE COMMENTS SECTION!!!!!! I met a smart guy once, who claimed that he was never wrong (stupid Ph.D. (Piled high and Deep)). He was one of the biggest jackasses I’ve ever met. So the next time you decide to leave a comment, leave a positive comment only. If you have nothing nice to say, don’t say anything. If you stupid math fools actually did this for a day you’d quickly realize that you will never have anything to say. Which would be a boon to mankind. -Stupid morons-

It should be 15. 49+15 = 64 8^2
This is simply the equality (n+1)^2 = (n+1)*(n+1) = n^2 + 2n + 1
(2n+1 is the next odd number).

Mathematik ist schön…
Mathematik muss nicht immer kompliziert und unvertändlich sein. Manchmal ist sie einfach nur mystisch und irgendwie wunderschön in ihrer Symetrie.
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
11111…
i love math.
These are really cool mathematical examples
The true magic of math is in its applications. Quantum Physics is pretty magical, but unfortunately it doesn’t have that easily understandable & instant “wow” factor that our attention-deficit society prefers.
“So the next time you decide to leave a comment, leave a positive comment only. If you have nothing nice to say, don’t say anything. If you stupid math fools actually did this for a day you’d quickly realize that you will never have anything to say. Which would be a boon to mankind.”
^Possibly the most hypocritical statement I’ve ever read.
Mathemagic…
Es gibt schöne Tage, schöne Erlebnisse, schöne Erinnerungen. Schön können Filme und Fotos sein, Malereien und andere Kunstwerke. Aber Zahlenreihen? Wie langweilig, deswegen frage ich mal so: Ist diese Symmetrie dieser Zahlenreihen nicht bemerkensw…
The integers are just chock full of mystery. Solving those mysteries is the realm of Number Theory. What amazes me is that EVERY branch of mathematics is used (and needed!) in Number Theory. Even Stephen Hawking admits, “God Created the Integers”.

two words: modular arithmetic. start there and work up to number theory
