Let N be a left near-ring and let be a function of N. We introduce the notion of two sided -n-derivation and prove that a prime zero symmetric near-ring involving -n-derivations satisfying certain identities is a commutative ring.Also, some examples are given to shown that the 3-primeness condition in our results is not redundant.
