I would make a sentence like this: "Learning to speak English is not boring, and it's not difficult either." "Isn't pretty, and it's not smart either." "Sally didn't give you the money, and I didn't give it to you either." In these sentences, "either" is like the opposite of "too". Jane *is* a teacher, and I am *too*. Jane *is not* a teacher, and I'm *not* either. --or-- Jane: I like apples! Bob: Me too! Jane: I don't like apples! Bob: Me neither! Hope that helps!

This sentence completes a previous statement: e.g., "Cooking oatmeal doesn't take very long." The listener then adds information: "It's not difficult, either." (I.e., "Cooking oatmeal is neither time-consuming nor difficult.") re. "not either": "The soup is not hot, but it's not cold, either." This could be two sentences in a dialog: A.: "This soup is not hot!" B.: "But it's not cold, either. It's just lukewarm."
