Required fields are marked *. How to retrieve minimum unique values from list? 1. 0 and 1. @Qwertylicious: If the question you're asking is how do you get $$v_0 + u_0 + u_2 + u_3 = 0$$ that's because $$v_0 = u_0 + u_2 + u_3$$ so $$v_0 + u_0 + u_2 + u_3 = (u_0 + u_2 + u_3) + u_0 + u_2 + u_3$$ which simplifies to zero, since the coefficients get reduced, mod 2. The idea is to think of the multiplication step as a parallel bit shift where every bit in the input is shifted by a different amount, specified in the constant. Binary multiplication is actually much simpler to calculate than decimal multiplication.
