Abstract : Let $R$ be a ring with a unity and let $M$ be a unitary left $R$-module. In this paper, we establish [5, Proposition 2.8] by showing the proof of it. Moreover, from the above result, we obtain some properties of direct projective modules which have the summand sum property.
Keywords : direct projective module, summand sum property, summand intersection property
