Having had a lot of spare time on my hands as of late, I have been yearning for a little more intellectual stimulation. I am a couple of years out of school and currently working in China. Always having a strong interest and passion for mathematics and physics, I feel that I could use my free time here to get my head down and hit the books. The stuff I studied in High School in my advanced maths class - algebra, functions, differentiation and integration and other basic calculus really interested me, and I was looking to pick up more or less where I left off. The trouble is that, living in an incredibly un-cosmopolitan Chinese city, there is absolutely nil chance of being able to browse around a bookstore for a decent textbook to get me going. As such, I've decided to jump onto Amazon and get a couple of books sent over. I figure that posting on this forum is perhaps the best place to get advice on what I should be looking at, and was wondering if anyone here could help me out with suggestions as to good textbooks. Any help is greatly appreciated.
