A stupid question ... about Math - Off-topic

I am sorry, i am not trying to get my homework solved by XDA member, but i counter this problem while doing homework.
The problem contains this : d^2y/dy^2 , i had no idea (I even failed to solve that question) what it is til i google it out

This really surprise me, because i never think that way, because the way they write the equation down drove me to a different way of thinking.
As you know xy^2 is not equal (xy)^2
so why the hell d^2y/dx^2 can be understand as d^2y/(dx)^2 ?
Because if we take the derivative of the f'(x) to get f''(x) , we will get d^2y/d^2x^2 not d^2y/dx^2.
I googled some more and look like this form is accepted by all sources:
So my question is, why could they write like that and never think that student could mistakenly think it as :"d^2 . y/d . x^2" ? Because if the student understand like that, it is not wrong based on the way they write it either.

and here have some photo, is that rooted?
As far as I know if you have superuser then you are rooted, have you tried an app that requires root to test? Like root explorer or titanium back-up?

the topic got no point , at least off topics got points
ppl post many posts on my thread \ people get to know me \ get xda friends etc
but this one got nothing , i mean come on , 7 billion this is so silly
Your mom is silly. Yes, I went there
Yeah the thanks meter on the side, i just noticed it wasnt working on mine and working on some. and oh boy an exaggeration, god forbid we put those in posts to spice things up a bit. it's not like i'm posting a problem with a rom....
I just realized the thanks meter probably means the amount of time you've been thanked...now the thread has no point... moderator delete at will lol
What just happened here?
Confused....

The best. Being a photographer, and when I used to visit a photo forum (lets just say the biggest) I hated it when people said I'm X years old. Because you are 12 that means you can suck in your work and have people praise you for it? I always loved to point out what the young people did wrong in their photos, and many of them quit. I remember being a photo noob, but I wanted people to tell me what is wrong with my work and try to improve on it. Now get back in paint and make those curves perfectly round.

I'm not entirely sure if this is better or worse than begging for Facebook likes..
Either way, it's probably against the rules, and completely pointless.

Is funny to view a counter full of flags.
