I'm having a very tough time understanding homomorphisms and ideals, probably because i'm very fuzzy with the concept of rings. I'm stuck on the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

Find all the ideals in the following rings:

1. Z

2. Z[7] (Z subscript 7, equivalence classes of 7 i'm guessing)

3. Z[6]

4. Z[12]

5. Z[36]

6. Q (set of rationals)

7. Z(this one wasn't written as a subscript, but as brackets, and "i" as the complex number i. what does that mean?)

Can someone help me to understand these better? I'd really really appreciate it.
