Ordinarily, this guy is correct, but this time he screws up:

"If you went to elementary school in the US, you almost certainly learned about the order of operations."

No, you didn't.

What he should have said was, "If your elementary school teacher was incompetent in math, she taught you this."Which is why we need to seriously rethink the training of teachers in this country.

"If you went to elementary school in the United
States (or much of the rest of the world), you almost certainly learned about something
boringly called the "order of operations"- a set of rules for whether or not you should
do multiplication before addition or addition before subtraction to get the right answer
on your math test.

I can't count as high as the number of times I had to unteach this concept learned in elementary and middle school.
