Typo correction: At 6:52, the screen shows
[x1, y1] + [x2, y2] = [x1+y1, x2+y2].
Of course, this should actually be
[x1, y1] + [x2, y2] = [x1+x2, y1+y2].

If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then "add subtitles/cc". I really appreciate those who do this, as it helps make the lessons accessible to more people.
