Let F be a field of characteristic not equal to 2.We describe the relation between the non-negative dimensional Milnor-Witt K-theory of F and the tensor algebra over the group ring Z[F×] of the augmentation ideal ΙF×.In the process, we clarify the structure of the additive group K1MW (F), in particular giving a simple presentation.
