I wrote a (very long) blog post about those viral math problems and am looking for feedback, especially from people who are not convinced that the problem is ambiguous.

It's about a 30min read so thank you in advance if you really take the time to read it, but I think it's worth it if you joined such discussions in the past, but I'm probably biased because I wrote it :)

The distributive law has nothing to do with brackets

BWAHAHAHA! Ok then, what EXACTLY does it relate to, if not brackets? Note that I'm talking about The Distributive LAW - which is about expanding brackets - not the Distributive PROPERTY.

a(b+c) = ab + ac

a(b+c)=(ab+ac) actually - that's one of the common mistakes that people are making. You can't remove brackets unless there's only 1 term left inside, and ab+ac is 2 terms.

ab+c = (ab)+(ac)

No, never. ab+c is 2 terms with no further simplification possible. From there all that's left is addition (once you know what ab and c are equal to).

brackets are purely notational

Yep, they're a grouping symbol. Terms are separated by operators and joined by grouping symbols.

Noted that you were unable to tell me what The Distributive Law relates to (given your claim it's not brackets).

You are unhinged
