Didn't do the question, was told he used some stupid name for an ideal that no-one uses, can't remember the exact wording, so sue me.
I'm pretty certain though, that given a ring R, you can say that an ideal of R is an R-submodule of R.
But you can agree that saying "consider an R-submodule", is a shitty way to denote an ideal, if only for brevity's sake.
