Does some degree of rounding? Sure. The degree you present? I don’t want to pay for (ca) 5 pounds of meat with (ca) 4.6 pounds. And again, this is a deflection of the point of general communication/ common understanding.

Yes, I understand that you think mathematical education is just a matter of telling kids how to punch numbers into the calculator on their iPhones and that any further thought about the relationship between those abstract functions and the real world is a woke waste of time

Sounds like a fun argument to have with a street vendor when purchasing food upon encountering less than careful rounding.

It is only by having some understanding of this concept that you would have any basis for having the argument!

My God I'm so fucking sick of conservatives ranting about "New Math" or "Common Core Math" as though the "good ol' fashioned cipherin'" they think is so important to teach kids isn't the *least relevant part of mathematical education by far*

It has never, in history, been less important to be able to recite your times tables It has never, in history, been less important to be able to take out a piece of paper and perform long division by hand

Even in the olden days before everyone was carrying a powerful computer with them in their pocket everywhere they went "Math errors" as the result of *conceptual* errors were far more common and damaging than actual arithmetic flubs

Forgetting to carry the 1 while multiplying two numbers gets you a wrong answer within the same order of magnitude as the right answer Multiplying the *wrong two numbers* is a far more consequential mistake

And the best way to build a foundation to avoid such errors is to start off teaching children to THINK To understand that mathematics, including even simple arithmetic, is a CONSTRUCTED TOOL Which is what all that newfangled nonsense about set theory and whatnot is about

It’s not constructed by us, it’s discovered.

It really isn't, or if you want to argue that the Platonic world of forms exists and a brain perceives it the way eyes perceive light you're getting really far into the philosophical weeds and taking that position isn't as easy as you seem to think

Couldn’t you just make the argument that “creation” is just discovery by another name implying ownership.
