    3. the ring of continuous real-valued functions on [0,1]
    4. the ring {a+b(sqrt(2)) : a & b are rational numbers}
    5. ring of polynomials in x with real coefficients

    What have you done on this yourself? Surely you don't want people to just give you the answers!

    I have just tried to find out some good online tutorials on Rings. When I think of rings, an empty circle comes to my mind...nothing else. I want to know the explanations of each & every points mentioned above otherwise I wouldn't have written them because I have the correct answer.
