[Noisebridge-discuss] Help with finite fields.

Hi Jason,

The notation / is pronounced "mod" and in both cases of your example
it refers to taking a quotient ring, which you can read about here:
http://en.wikipedia.org/wiki/Quotient_ring

The notation of [T] refers to creating a polynomial ring by throwing
in a new element T (so, all the elements of the new ring (Z/2Z)[T] are
polynomials where the coefficients are from (Z/2Z) and the variable is
T)

Yours,
Brown
