And furthermore when he wants to write 25, he writes it as 52 with
reversed 5 and 2. So if you look at it in the mirror, it's 25!
Is there something wrong with his brain of some kind of illness?

I always wondered this.

In math there is addition, multiplication, and powers, and they are reversed with subtraction, division, and logrithms, respectively. They are also connected like this:

in Powers, 4^5 is simply, 4*4*4*4*4,

and in multiplication, 4*5 is simply 4+4+4+4+4

So my question is...is there a function past powers, for example

4^4^4^4^4 can be simplified into a new type of function. Does this type of function exist? Obviously this is a ridiculously large number, but I thought that maybe there might be a theoretical use for it...

It was all dark and cloudy and rainy today, and I realized it made me feel sort of depressed and sad, lonely, moody, and pessimistic. Does weather affect your mood too?

And the same way in which smells can have memories attached, or can evoke memories in a powerful way, does any weather affect you that way too? Like for me, when I think of windy autumn days with leaves blowing in the wind, and when I actually experience that weather in the fall, it makes me depressed because I once was going through a difficult time during that season, and whenever I think of it or feel that weather, it makes me sad.

Would anyone be able to help me with this question?

For the polynomial:

P(x)=x^5-x^4-10x^3+2x^2+16x-8, I have been told that two factors are (x-1) and (x+2) and I have to show that one of these is a double factor...how do you do that? I know that a double factor means that it's a perfect square (i.e. (x-1)^2 or (x+2)^2) but that's all...I would really appreciate some help...can anyone explain this to me? Or show me a website that will? Thanks so much! :D

I mean really really know the CHEMISTRY of memories... Not WHERE in the brain, or How the brain changes when it is storing something in memory, or how the brain breaks the memories up into separate parts... I mean what chemically makes a memory? What would it take to move a memory from one brain to another, like moving a file from one computer to another...

From everything I have seen and read, no one really knows. Is this true?

I mean if you don't accept evolution as fact then why accept creationism as fact? Can't the two work together? I mean the Bible can't be 100% right when it wasn't even written all at the same time. Why's it okay to question evolution, but not creationism? And if God used His powers to keep the writings of the Bible intact after all these centuries, wouldn't that be effecting freewill? Why would He be so tricky? He wants to give everyone a fair shot at Heaven right?

Really sorry for being the 5000th person to ask this.
