# 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. Cool stuff that being smart isn't really knowing everything, It's mostly about knowing if you know.



Sometimes I like to explore mathematics, such as this, this or this. And sometimes I write it in a poor way because of my lack of knowledge. I expect people not to hate me for such explorations.

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.
