Yeah, but even worse, you’re just talking about schools
I'm talking about anyone at all in the U.S. is allowed to teach Maths without any Maths qualifications
You forgot about all the kids being home schooled
That happens in other countries too, and yet it's the U.S. which has been sliding down the world rankings for more than a decade, the country that doesn't require Maths teachers to have Maths qualifications.
Also, it’s kinda obvious the rules of math aren’t different in the US
That's right, as proven by U.S. Maths textbooks
If people don’t know how to use math properly, the issue clearly is the education and not math itself
Partly right. there's also people who just outright forgot the rules.
