... With the last two steps, one can define the inverse of a non-zero element x ∈ O by x x−1 := N (x) so that xx−1 = x−1 x = 1. Since x is arbitrary, O has no zero divisors. Upon checking that x−1 (xy) = y = (yx)x−1 , the non-associative algebra O is turned into a division algebra. Since N (x) ≥ 0 for a ...
