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 :)
It ISN'T a notation for multiplication - it's a notation for a factorised term, and if you ignore The Distributive Law going back the other way then you just broke the factorised term dotnet.social/@SmartmanApps/110886637077371439
This one already does have no ambiguity.
