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 :)
That you're still wrong? As I said, the true answer is that the problem is written poorly due to the obelus and thus is open to interpretation. You're entitled to your own interpretation since it's written poorly, I just find it pretty obviously less logical than multiplying using the distributive property first to resolve the term with the parentheses fully as you would in any advanced math.
Also, distributive law and distributive property are the same thing per Khan academy "The distributive property is sometimes called the distributive law of multiplication and division."
Wait till you hear that "i before e except after c" wasn't true either. It's wild that you think 7th grade math overrules grad school math though lol.
About? You haven't pointed out anything that's wrong.
Oh, you're one of those people. Good, maybe we can finally get an answer then (this was also talked about in the blog). What other interpretation of an obelus is possible other than division? People keep saying it's ambiguous, but no-one has ever said why (other than some stuff that makes no sense in the context, as explained in the blog)
Yes, and sometimes people call Koalas "Koala bears", but that doesn't mean they're bears. Now bearing that in mind, read again what Khan said - the page which is called "Distributive property explained", not "Distributive Law explained".
Wait till you hear that's not a rule of Maths.
Umm, never said anything of the kind...
