Questions about the questions in the exercise section



Hello I have a question about the solution in this question
Link to the exercise in the video: https://www.coursera.org/learn/classification-vector-spaces-in-nlp/lecture/g6fge/manipulating-words-in-vector-spaces
Accordingly
Japan (4,3) + [5, -1] = (9,2) β†’ Ankara (9,1): Distance d = 1
Turkey (3,1) + [5, -1] = (8,0) β†’ Ankara (9,1): Distance d = sqrt(sqrt)
So according to this question Ankara is the capital of Japan. Is there something wrong in my solution or the question. Thank you very much
