Ok, How does this come out to three, I understand how I got it, but why is that always the rule?

Start with a number and multiply by 4. Add 6 to that, and divide the answer by 2, then subtract 2 times the origional number.

for example, # = 10
10 x 4 = 40
40 + 6 = 46
46 / 2 = 23
23 - (2 x 10) =
23 - 20 = 3

why does it always work out to be 3?

Ok most of you are going to be disappointed but here is how I think it could happen
Let’s say you were taken to space to the nearest star Alpha Centauri and you met some sexy aliens, had fun and stuff. Then when your time is up NASA sent you back to earth and after a while you started to miss that sexy alien and rewind some memories you two had back then. Now when you keep thinking deep and deeper you would almost feel like you were physically there, it is clearly visualized in your head, all the sound the sensation, the smell everything is coming back to you. Finally you make it all the way to Alpha Centauri with in a few minutes you are there. Now the question is how long did it take you to reach there? Like I said just a few minutes right? But how long does it take for light to reach earth from Alpha Centauri, almost three years.
So if we could scientifically discover what these thinking substances are then we would know they are definitely faster than photons or particles of light.
You get my point right?

last year i was researching about global warming and i found a graph showing the worlds temperatures for hundreds of years. It showed that the temperature of the world went up and down (down being an ice age). It shows that we are in a hot period at the moment and its not all due to pollution
