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 :)
Just write it better.
6/(2(1+2))
Or
(6/2)(1+2)
That's how it works in the real world when you're using real numbers to calculate actual things anyways.
But how would that go viral?
If you really wanted extra brackets it'd be 6/(2)(1+2). Of course, since there's only 1 term in the first brackets they're redundant, hence 6/2(1+2) is the fully simplified form, and is the way it's written in Maths textbooks.
