Algebra, chapter II, § 7. Vector spaces

For every AA-module EE, E/T(E)E/T(E) is torsion-free.

If f:E→E′f : E \to E' is an AA-linear mapping, let fTf_T denote the mapping T(E)→T(E′)T(E) \to T(E') with the same graph as the restriction of ff to T(E)T(E). With this notation:

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