Hey welcome to the forums.

I have the CX CAS too but I never figured out how to do that.

I noticed that it does integer division when there is no "." well not totally integer division but it leaves it in fraction form if there is a decimal.

I also noticed that when finding the vertex on a graph it will only give you a couple numbers after the decimal while on a TI-84+ it will give you so many more places after the decimal point.

I know that this doesn't answer your question but they were just things that might help try to figure it out.

Eh my classes are weak compared to you guys.

I have Spanish 3 Honors , AP Computer Science(in Java), AP Chemistry, American Literature, Analysis Honors, U.S. History, and lastly Beginning Piano.

This is awesome!  Too bad I don't have a clickpad to try it out on.

I'm learning to play it now

EDIT: @Nicco I like some of the features of stock like the auto-wifi finder, but I would also like Jelly Bean. I also am worried about this because I don't want to brick my $400 phone.

I was afraid of bricking my phone too.  It usually isn't a problem though.  Just read the directions word for word and read through a lot of forums about it.  You just need to make sure that you know what you're doing before you do anything and if things do go bad and you do brick you can usually ask for help to get it unbricked except lots of android forums hate noobs for some reason.  I have an account on XDA Developers but I never use it, probably for that reason because I'm somewhat of a noob and I'll just get hated on.

I'm taking a Piano/Keyboard class at school and all we do is sit and play through a book that they provided for us.  I seem to be learning alright.  You should probably head to a music shop nearby and pick up a beginners book.
The book that we use is <a href="http://www.amazon.com/Alfreds-Basic-Adult-Piano-Course/dp/0882848321">Alfred's Basic Adult Piano Course</a>.
We also use a theory book called <a href="http://www.amazon.com/Alfreds-Basic-Adult-Theory-Piano/dp/0882846353">Alfred's Basic Adult Theory Piano Book</a>.
I think I've been learning alright and the teacher doesn't really teach much so I've just been learning from the book.

I have a guitar and I kinda want to learn to play but it's So Hard!
I used to play alto sax in band so I can read music pretty well but guitar is just tough to learn.  I also haven't really actually tried though.

Anyway good luck on learning to play.

I got some money because my parents didn't know what to get me and a Raspberry Pi case.

Merry Christmas everyone.

Hey. Welcome to the forums.  I doubt that I'll be able to help you but hi anyway.
I guess I need to give you some peanuts so here they are.
