... Consider now h = x∈F x = 06=x∈F x. Choose an element x ∈ F which is not zero and not equal to 1 (we are using the fact that Z mod 2 6= F ). Now, the elements F \ {0} form a group under multiplication, so multiplication by x permutes the elements of F \ {0}. Therefore, xh = h. In particular, because ...
