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 :)
My years out of school has made me forget about how division notation is actually supposed to work and how genuinely useless the ÷ and / symbols are outside the most basic two-number problems. And it's entirely me being dumb because I've already written problems as 6÷(2(1+2)) to account for it before. Me brain dun work right ;~;
There's no forms consensus on which one is correct. To avoid misunderstanding mathematicians use a horizontal bar.
The one that is least ambiguous is objectively more correcter.
Only if it's a fraction. If it's 2 separate terms then you use whatever your country uses for division - obelus or colon or whatever. They have to be 2 separate things, otherwise how would you write to divide by a fraction?
