## The Attempt at a Solution

For the first half of the question, ordered pairs would be (1, [1]), since 1 and [1] are the multiplicative identities in these rings. but no matter how many times we add (1, [1]) to itself, we'll never get (1, [1]) again. does this mean this ring has zero characteristic?
