# Define this please (possibly polynomial rings) watch

1. What does this mean:

or is it:

I think it is something to do with polynomial rings.

Cheers
2. is the polynomial ring (of one variable) over the ring R. So would be the polynomial ring over the real numbers, which is also a ring.

As for the subscript 1, I've never seen that before in this context. Where did you get it from?

I got it from some scribbles I made in my lectures, otherwise it would have been easy to figure out what it was as it would have been defined by my lecturer. I am not sure, I thought maybe it was the order of the polynomial...
4. I'm sure your lecturer would have noted the significance of the subscript if he wrote it there. Aren't there any online lecture notes?

It might have been . You can have polynomial rings in several variables which you could write as
6. I have found it about five pages on:

is NOT a ring: multiplication is NOT closed.

That is all I can find on it... Thank you for defining the difference between and though
7. So all polynomials of degree 1 or less.

Yes I would say so, that is literally the only line I have.
