alt Hacker NewsI think you're misunderstanding the question — possibly for comedic effect (?), it's hard to tell.
"zeroes" is the plural form of the noun "zero", yes. But the question is about using the form "zero" as an adjective and how that should affect the plurality of the noun it applies to: "zero book(s)", for example.
I am not trying to be funny. It seems to me that you are misunderstanding the usage of the word zero in this context, as in absence of any. Synonymous to "no", as in "no threes".
It is not about the number 0.
