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 :)
I disagree. Without explicit direction on OOO we have to follow the operators in order.
The parentheses go first. 1+2=3
Then we have 6 ÷2 ×3
Without parentheses around (2×3) we can't do that first. So OOO would be left to right. 9.
In other words, as an engineer with half a PhD, I don't buy strong juxtaposition. That sounds more like laziness than math.
Yeah, but implicit multiplication without a sign is often treated with higher priority.
Is it though? I've only ever seen it treated as standard multiplication.
