# Hello!

I am self-learning mathematics at the moment. My interest on mathematics was completely destroyed in high-school, after years ignoring it I've discovered it's interesting and beautiful. Now I'm planning to study it on university and even pursue a masters and a Ph.D! Yay!

I am very grateful for your $Time \cup Patience \cup Answers$. If my question is too stupid, blame these answerers.

Sometimes I do ask somethings that must be understood as obvious - this is perfectly normal: Some time ago I presumed that the factorial of $0$ is $0$, because I was following the pattern: $3!=6$, $2!=2$, $1!=1$ - $0!$ had to be $0$. I even thought that the guy who wrote the article saying that $0!=1$ was a complete dumbass, then I discovered I was the dumbass. This made me accept that I know nothing and things that are regarded as obvious sometimes aren't - I prefer to ask such obvious stuff than to carry a wrong intuition about it.

If you want to talk, you can e-mail me: $gioxis@gmail \cdot com$

I am also a pseudo musician, I study piano and I used to make music with my computer.

Nov27 comment How to use dd to make splitted ISO images from an storage device? @Paul It's impossible, it's a iPod touch (3rd generation), it's impossible to do the way you suggested - I've searched for it and this was the only way I've found.

Look the examples I just posted now. Oct5 revised Is it possible to make Adobe Reader to only negate a page? added 226 characters in body Oct5 comment Is it possible to make Adobe Reader to only negate a page? It seems there's a separation on Adobe Reader: Things that are background and things that are text, strangely, that line is not considered as text. Also notice that there are a lot of similar errors in other parts of the book. There's also another case: When a PDF book is made of scanned images, the negation does not occur in these scanned images. Oct5 comment Is it possible to make Adobe Reader to only negate a page? Nope. Did you notice the line almost disapeared? If you read it with less zoom, it's impossible to see the line.
