# Math Help - Two questions about modules.

1. ## Two questions about modules.

Hello friends, abstract algebra is not my cup of tea so I was wondering if you could help me to solve these two exercises.

1.- Let $R$ be a commutative ring and unitary. Prove that $R$ is a R-module.

2.- Let M be a R-module and let N be a R-submodule of M. Prove that the canonical homomorphism, $c: M ---> M/N$ defined by the formula: $c(m) = m + N$, is a R-epimorphism with kernel N.

Thank you SO MUCH

2. Okay, what is the definition of "R- module" and what is the definition of M/N?
