Algebra, chapter V, § 1. Prime fields. Characteristic

— We still have S=KS = K when the additive group of K is torsion-free; this follows from the above proof or from Remark 5 of V, p. 3.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
