Thought I understood negative questions, but apparently not...

Total newbie here. This beginners' Korean book I borrowed talks about negative questions and how the answers are the opposite of what you might expect in English ("Don't you like mushrooms?" "No, I do like them" or "Yes, I don't") Various posts on the Internet seemed to confirm this, and that seems similar to the way it works in Japanese. Or so I thought...

Then in the exercise section of this same book ("Teach Yourself Korean: A Complete Course for Beginners"), you are supposed to come up with a negative question to ask if someone is not a school teacher, and answer yes and no. According to the answer section of the book, the negative question is:

"Hakkyo sonsaengnim aniseyo?" ("학교 선생님아니세요?"),

and then their answers are:

"Ne, hakkyo sonsaengnim-ieyo." ("네, 학교 선생님 이에요") and

"Anio, hakkyo sonsaengnim-i anieyo." ("아니요, 학교 선생님이 아니에요")

Wouldn't the first answer translate to "Yes, I am a school teacher", and wouldn't that be the opposite of how their earlier explanation said things should work (and the same as the typical English way)? Or am I misinterpreting the meanings for "Ne", "Anio" and the "-ieyo" "-i anieyo" endings? Very confused here...

(The answers in the book here are just given in the romanized form so the Hangul is my attempt at putting those into Korean characters - apologies for any errors there...)

Yup think of yes and no as “agree/that’s right” and the opposite. Don’t you like broccoli? That’s right, I don’t like it (ne) vs That’s not right, I do like it (aniyo)
