Math problem that is driving the Internet crazy

[Haipule]

This is a simple duplication problem that non of you can see. 1 + 1 = 2, 2 + 2 = 4, 4 + 4 = 8 and 8 + 8 = 7, 16 + 16 = 32 (7 + 7 = 5) which is 5 and 5 + 5 = 1. So, the sequence 1,2,4,8,7,5 is infinite as long as there is no number higher than 9. I hate 10 because it is 1! What about 3,6,9? PLEASE tell me! Sorry, the answer to your question is 7--duh!

3 and 6 spin together forever, of course. 9 is stuck, because you don't get anywhere by doubling 9.

I see, 363636 or, 636363. Funny how every multiple of 9 = 9 and how the numbers just invert:

09 18 27 36 45 
90 81 72 63 54

So 9 is stuck in it's own world and rules. Therefore, God = 9. Here is my equation proving, beyond a shadow of doubt, that God exists: G = 9


You heard it here first!

I think I've spotted part of your problem.

There is no number higher than 9. So, 8 + 8 = 16 or, 1 + 6 = 7--DUH! Just like 16 + 16 = 32. Not so fast as 3 + 2 = 5 or, 7 + 7 = 14, 1 + 4 = 5 as there is no higher number than 9. Then 32 + 32 = 64. There is no number higher than nine so 6 + 4 = 10. There is no number higher than nine so, 1 + 0 = 1 and 64 + 64 = 128, 1 + 2 + 8 = 11 there is no higher number than nine so, 1 + 1 = 2. Get it? It's a fun toy to play with and it is infinite. 1,2,4,8,7,5,1,2,4,8,7,5 it never ends.

It's called modular arithmetic base 9. This works because the remainder when you divide 10 (the base of our number system) by 9, is 1.

There are a lot of 'magic tricks' that are based on this.

You can do similar thing with multiplication by 5 to get 5, 7, 8, 4, 2, 1, 5, 7, 8, 4, 2, 1,... Notice that these are your sequence with order reversed.

Or multiply by 7 each time: 7, 2, 5, 8, 2, 5, 8, ... Note that these are every other one from the previous.

Or you can take any two numbers, say 384 and 927. Multiply them to get 355968. Now, "reduce all by 9's": 384=15=6 and 927=18=9. Now, 6*9=54=9.
But, 355968=3+5+5+9+6+8=36->3+6=9, the same answer. And you will always get the same answer (but not always 9).

As soon as I read "8 divided by" it made in a fraction with 8 the only number in the numerator, the answer 1.

Thank God I'm not the only one playing with these toys! Shall we go into fractal geometry!? There is just something about infinity that is so damned appealing!

I'd point out that 9 is only important here because we work in base 10=9+1. If we worked in base 16, then 15 would be the relevant number.

Fractal geometry? Sure. But a LOT of the popular stuff out there is more 'gee whiz' than actual math. Once you get to the concept of a fractional dimension for a metric space, we have something to talk about.

And if you want to talk about 'infinity', I'd suggest learning some set theory first.

At work.

*Sees ridonculous comments.... *

*Flees in panic at the sight of such mind melting concepts....... *

Yes, fractal geometry, not too dissimilar to the Fibonacci sequence in numbers making numbers making more numbers as a spiral such as the human ear or a hurricane, is the beautiful math of nature. Yet, fractal geometry was developed to measure the coastline of England with something smaller than a ruler by a guy who worked for IBM named Mandelbrot with his set also showing the fractal beauty of nature including biology.

Yet vortex math is to me a toy until you polarize it.

This makes sense to me:
8/2(2+2)
8/2(4)
8/8
1

This kind of makes sense to me:
8/2(2+2)
4(2+2)
4(4)
16

[Agnostico]

What is the correct answer to:

8 divided by 2(2+2)

The answer i get is 16
