6÷2(1+2)
(programming.dev)
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 :)
And note that it doesn't work if the multiply was an addition. e.g. 6/2+3=6 but 6+3/2=7.5. Multiplication and division are both binary operators, and you can't move them around unless you also move the term to the left with it. i.e. 6/2+3=6. 3+6/2=6.
No, to the left of the 6 is an actual plus sign, but we don't write plus signs if it's at the start of an expression. +6 and x6 aren't the same thing at all (and, since x is a binary operator, you couldn't write just x6 anyway - there would have to be a term to it's left). No expression ever starts with x6.
It's not a valid notation for multiplication either - both multiplication and division are binary operators and must be written with 2 terms.
