That's the sort of thing "new math" was trying to teach. Those sorts of breakdowns are exactly what the kids who were good at math were always doing, and teaching methods eventually caught up and realized they should just teach the tricks.

Then a bunch of parents who were bad at math asked "new math? How can math change?" The fact that they even asked that question showed how their math education was lacking, but they seem to have won.

I was trying to explain how and why they were teaching math to a family friend and they didn't get it(multiplication stuff). I broke it down with pen and paper and they didn't get it. Simpler example, nope. Eventually I had to explain how multiplication is just repetitive addition. They responded with WHAT! and I realized why they always wore open toed shoes. I sent them a link for 5th graders.

I'm not very good at math (but not an idiot like your example) and I wear flip-flops every day of the year but they're not related.

Are you trying to say something like "too dumb to tie shoelaces?"

Because there are quite a lot of lace-up open toe shoes and sandals, as well as closed toe shoes without laces, so that doesn't track.

Can you count to 20 with your shoes on?

I can count to 20 with my eyes shut but my toes can't breathe with shoes on.
