Well, I am actually studying Engineering, Electronics and Communication Engineering to be specific.

But I am extremely fascinated with Mathematics as a whole, and I occasionally try to pass time by complicating the simple things and stuff, it's some joy for me.

To someone reading this introduction, I would be glad if you could direct me to a particular source material to read and practice that would help me in acquiring enough mathematical knowledge as a whole. I know it's a vast subject and I need to be specific, but.... that's that.
