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 :)
The examples I gave were that the expansion of brackets would be done differently if the order of operations was "PESADM"; and I also drew your attention to the fact that reverse polish notation exists, in which there are no brackets at all and the order of operation is entirely determined by the order that operators appear, with no hierarchy of operations. As for your appeal to authority, let me just say that your level of qualification on this topic is not above mine. It adds no weight whatsoever to your argument.
I just glanced at your post history to get a sense of why you were so engaged in this. I was a bit startled to see that you've been on a bit of a posting spree in this thread, which I point out to you is a 3 month old post on a 'memes' channel. I see you've taken issue with a lot of what people have said here. My suggestion to you now is that there probably won't be a lot of engagement in this thread from this point on. So perhaps you should just ponder what is said, and prepare yourself again for next time this comes up. Perhaps you can start by seeing if you can get a consensus amongst fellow experts in a maths channel or something, because at the moment it seems like you're on your own.
Yep I read it, and no it wouldn't. Expanding Brackets - or in the case of this mnemonic Parentheses - is done as part of B/D (as the case may be). i.e. expanding brackets isn't "multiplication" (no multiplication sign), but solving brackets (there are brackets there), which always come first in all the mnemonics.
...but is not taught in high school.
Maybe not, but it means it's not an "appeal to authority" (as per screenshot). Maths teachers ARE an authority on Maths. The most common appeal to authority I see from people is claiming that someone (not them) is a University professor, and "they would know". No, they wouldn't - this topic isn't taught at university - it's taught in high school.
I'm a teacher. You say you're on the same level as me - don't you like to teach people what's correct?
Which will show up in search results for all eternity (it's how I found it - I was looking for something else!).
Got another 12 responses after yours. But the point is I'm not even LOOKING for responses, just to correct misinformation. As a teacher (a Maths teacher?) have you not had people say to you "But Google says"? I certainly have. It's the bane of my professions.
Did you read my thread? Maths textbooks, calculators, proofs, etc. Also, someone else said what you just did, asked a Maths teacher, and was told I was correct, then was man enough to go back and edit his posts and admit I was correct and specifically said "SmartmanApps is not on his own with this".
