Exercise 6.1: Let $M$ be a module over a ring $R$. Show that $M$ is a direct sum of cyclic modules. Exercise 6

Solution: Let $m \in M$. Consider the set $Rm = {rm \mid r \in R}$. This is a submodule of $M$, and $M$ is a direct sum of these submodules. Herstein is a classic textbook in abstract algebra

For students who want to check their answers or get more practice with the exercises, we provide a downloadable PDF solution manual for Chapter 6 of "Topics in Algebra". The solution manual includes detailed solutions to all exercises in the chapter.

Solution: Suppose $A$ is simple. Let $I$ be an ideal of $A$. Then $I$ is a submodule of $A$, and since $A$ is simple, $I = 0$ or $I = A$.
