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 :)
Citation needed.
If I have to search your 'source' for the actual source you're trying to reference, it's a very poor source. This is the thread I searched. Your comments only reference 'math textbooks', not anything specific, outside of this link which you reference twice in separate comments but again, it's not evidence for your side, or against it, or even relevant. It gets real close to almost talking about what we want, but it never gets there.
But fine, you reference 'multiple textbooks' so after a bit of searching I find the only other reference you've made. In the very same comment you yourself state "he says that Stokes PROPOSED that /b+c be interpreted as /(b+c). He says nothing further about it, however it's certainly not the way we interpret it now", which is kind of what we want. We're talking about x/y(b+c) and whether that should be x/(yb+yc) or x/y * 1/(b+c). However, there's just one little issue. Your last part of that statement is entirely self-supported, meaning you have an uncited refutation of the side you're arguing against, which funnily enough you did cite.
Now, maybe that latter textbook citation I found has some supporting evidence for yourself somewhere, but an additional point is that when providing evidence and a source to support your argument you should probably make it easy to find the evidence you speak of. I'm certainly not going to spend a great amount of effort trying to disprove myself over an anonymous internet argument, and I believe I've already done my due diligence.
So you think it's ok to teach contradictory stuff to them in Maths? 🤣 Ok sure, fine, go ahead and find me a Maths textbook which has "weak juxtaposition" in it. I'll wait.
So you're telling me you can't see the Maths textbook screenshots/photo's?
Lennes was complaining that literally no textbooks he mentioned were following "weak juxtaposition", and you think that's not relevant to establishing that no textbooks used "weak juxtaposition" 100 years ago?
It's in literally the first textbook screenshot, which if I'm understanding you right you can't see? (see screenshot of the screenshot above)
Ah, no. Lennes was complaining about textbooks who were obeying Terms/The Distributive Law. His own letter shows us that they all (the ones he mentioned) were doing the same thing then that we do now. Plus my first (and later) screenshot(s).
Also it's in Cajori, but I didn't find it until later. I don't remember what page it was, but it's in Cajori and you have the reference for it there already.
Well I'm not sure how you didn't see all the screenshots. They're hard to miss on my computer!
You haven't provided a textbook that has strong juxtaposition.
That's not a source, that's a screenshot. You can't look up the screenshot, you can't identify authors, you can't check for bias. At best I can search the title of the file you're in that you also happened to screenshot and hope that I find the right text. The fact that you think this is somehow sufficient makes me question your claims of an academic background, but that's neither here nor there. What does matter is that I shouldn't have to go treasure hunting for your sources.
And, to blatantly examine the photo, this specific text appears to be signifying brackets as their own syntactic item with differing rules. However, I want to note that the whole issue is that people don't agree so you will find cases on both sides, textbook or no.
You are welcome to cite the specific wording he uses to state this. As far as I can tell, at least in the excerpt linked, there is no such complaint.
Here you go - I found I did save a screenshot of Cajori saying ab and (ab) are the same thing - I didn't think I had.
