or, if you want to work in octal, 6 x 4 = 30
in hex, c x 4 = 30.
We could go on and on in alternative number systems.

Sure, that's true, and it's also the correct answer if the question was "what's an equation that equals 28", but neither one of those questions is what was asked.

--4 times 7 is 30 if you want your answer rounded to the nearest multiple of 10.

If that's what they're talking about, they're doing a very poor job of explaining themselves. You can certainly ask a question that has multiple correct answers, but there are still right and wrong answers... there might be 50 right answers instead of 1, but the infinite number of wrong answers are all still wrong. 10 times 3, 15 times 2 and 5 times 6 can all be correct answers to that question, but 4 times 7 is always going to be wrong.

Both those references are pretty alarmist. Here is what they cite. While I may be too old and biased for their wokeness, they raise some very valid points. IMHO the focus of learning math should be on understanding math and we are doing a whole lot better at that now then when I was in school.
As to the original point about "correct answers", it seems that this a misconstrued interpretation of the focus on divergent thinking. Give me three equations that equal 30 does have multiple correct answers and is a much better question then what is 10 times 3.https://equitablemath.org/

Theoretically, someone could keep thinking about this problem forever and generate infinite correct answers."

--Just read of a push to teach a “new math” the encourages multiple “correct answers” to math problems and eliminates “show your work”. Supposedly cleanses math teaching from institutional racism.OK, irrespective of your genetics, heritage, cultural backgropund and gender choices, if I tell an employee to go read the sequentials off of a reel of cable and tell me how much is left, they better get one frigging answer, the one and only correct answer.So I am an old fat entitled unwoke white guy. By some accounts automatically racist. I don’t feel that way, but again I am unwoke (whatever in the hell that means) so I wouldn’t know.I simply don’t get how getting the one and only right answer in math class is institutional racism. Can you imagine someone that came up through schools that allow this trying to get into an engineering program? Now who is suppressing whom...
