Perhaps you missed seeing the “Tips and Notes” that Duolingo included with the Determiner lesson. If you’re just using the Duolingo App, you won’t be able to see any lesson notes. They can only be accessed from Duolingo.com. Here's what Duolingo says about double negatives:
Standard Hebrew, like many other languages, makes use of double negatives ("he didn't do nothing", rather than "he didn't do anything"). Therefore we say:
I don't see "no one" (anybody) = אני לא רואה אף אחד I don't see "no thing" (anything) = אני לא רואה שום דבר שום דבר is the same as כלום (nothing).
you can also see all tips and notes (along with your progress) @: duome page: https://duome.eu/USERNAME/progress
