comment Multiplication in the field $F = \mathbb{Z}_2[x]/f(x)$
About your note, you're right my answer in (1) should be $(x^5+x^4+x^3+x^2+1)$ since it's mod 2.

Thanks for the explanation, I think I understand it better now. $(x+1)(x^5 + x^4 + x^3 + x^2 + x) + 1$ was what I got but I wasn't sure that $(x^5 + x^4 + x^3 + x^2 + x)$ was the inverse, I see it now.

Ops, I guess I was tired when I wrote it. Of course they divide N and are relative prime to each other.
