@JoséCarlosSantos Easily fixed. =)

@JoséCarlosSantos May I know why you voted "looks OK" in the above review?

@YuiToCheng It was a mistake. I've just downvoted it and flagged it as “Not an answer”.

@JoséCarlosSantos Thanks!

cv-pls linear-algebra Missing context or other details; if one "understands how the proof works," then the intuition is there. :\ Determinant of a matrix with 2 equal rows‭ - Joseph‭ 2019-04-23 11:12:30Z

What the asker actually means, I think, is that they follow each step of the proof, but don't actually understand how those steps actually work together to give the proof.

The question is a PSQ from the HNQ, by the way.
