6÷2(1+2)
6÷2(1+2)
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 TI-84 Plus is my holy oracle, I will go with whatever it says.
And then get distracted and play some Doom.
It will give 9, just like my 89 emulator. The entire denominator of a fraction needs to be in parentheses or you get into trouble and it treats division like a fraction.
It treats division like a fraction
Which is why it gives the wrong answer.
Also you shouldn't be adding a dot between the 2 and the brackets - that also changes the answer.

TI calcs give the wrong answer, and it's in their manual why - they only follow the Primary School rule ("inside the brackets"), not the High School rule which supersedes it (The Distributive Law).
