In a question you say that ${none eq 0} will be evaluated to true because the value of the attribute none is "". I've tested it and it prints false.

As per Section 1.18.3 of Expression Language Specification:
Coerce A to Number type N
¦ If A is null or "", return 0.
Therefore, the given answer is correct.

I think they mean when adding, substracting ... but not for equal
${"" eq 0 } prints false
${"" + 10 } prints 10
${"" * 10 } prints 0
