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.
Itβs about a 30min read so thank you in advance if you really take the time to read it, but I think itβs worth it if you joined such discussions in the past, but Iβm 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 βPESADMβ
Yep I read it, and no it wouldnβt. 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 isnβt βmultiplicationβ (no multiplication sign), but solving brackets (there are brackets there), which always come first in all the mnemonics.
reverse polish notation exists
β¦but is not taught in high school.
your level of qualification on this topic is not above mine
Maybe not, but it means itβs not an βappeal to authorityβ (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 βthey would knowβ. No, they wouldnβt - this topic isnβt taught at university - itβs taught in high school.
why you were so engaged in this.
Iβm a teacher. You say youβre on the same level as me - donβt you like to teach people whatβs correct?
3 month old post
Which will show up in search results for all eternity (itβs how I found it - I was looking for something else!).
probably wonβt be a lot of engagement in this thread from this point on
Got another 12 responses after yours. But the point is Iβm not even LOOKING for responses, just to correct misinformation. As a teacher (a Maths teacher?) have you not had people say to you βBut Google saysβ? I certainly have. Itβs the bane of my professions.
it seems like youβre on your own
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 βSmartmanApps is not on his own with thisβ.
