I studied math all by my self for a few years out of my own love for it, since without guide, I was often puzzled.
I'd like ask for aid here, mainly about why we view numbers over spec Z etc. Does it or how does it be "nature", I myself was trying quite hard to get a feeling about this. I'd also appreciate if you could offer me a little examples,a link to some short note would be excellent,by the way, if it's convenient, my email is email@example.com . Thanks a lot.
