Generating a Commutative Ring
Not what you're looking for?
Let a commutative ring R be generated by {a_1, a_2, ..., a_n}
such that [a_1, a_2, ... , a_n] = {(a_1xr_1) + (a_2xr_2) + ... + (a_nxr_n) for
r_1, ..., r_n in set of Reals}.
I need to show this set is an ideal. Do I just need to show that it satisfies the commutative properties of the ideal?
