Algebra, VIII, p. 190, § 11. Grothendieck Groups

The set $K(\mathscr{C})^+$ is the submonoid of $K(\mathscr{C})$ generated by the family $([S]_{\mathscr{C}})_{S\in\mathscr{S}}$ .

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
