Hi Jonathan!

Thanks for your comment! You're completely right. Since -25+19 = -6, we should actually have n = s + 6. I've let editors know about the mistake, so that it can be corrected.

Please note that because we're a small team with many projects going on, it may take a while for a new video explanation to be uploaded. Fortunately, in the meantime, the general approach used to solve the problem leads us to the correct answer, despite the addition mistake :)

Thanks again!

-25 + 19 = -6, not -7
