While we’re at it, why don’t we have the TEKS standards for arithmetic look at the strengths and weaknesses of the times tables?
Strengths: it’s right. It makes sense and it’s internally consistent. It’s handy. It can be extended by well understood algorithms.
Weaknesses: unlike a kitchen table, if you do your homework on it, it’s ruined.
Appalling weakness: you might get to thinking about how easy it is to run into big numbers like billions, and that might get you thinking about billions of years, and how could there be light from galaxies that far away, just now arriving, if there was never any sufficiently deep past for that to have happened.
