Commutative Algebra, chapter I, § 2. Flat modules

With the hypotheses of Proposition 6, E⊗AF′E \otimes_A F' is usually identified with ϕ(F′)\phi(F') for every submodule F′F' of FF, which gives the formula

E⊗A(F′∩F′′)=(E⊗AF′)∩(E⊗AF′′). E \otimes_A (F' \cap F'') = (E \otimes_A F') \cap (E \otimes_A F'').

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