66. See anything in this link that rings a bell as to something taught in a strange way?

I'm not trying to create stress or to push you to "explain it in detail", but I thought that if you had an example in front of you it might be easier than scanning and posting (would be for some). I didn't know it was that long ago and examples were not at hand.

I'm just curious, because I have taught math in the past and like it and think about it and have looked into the philosophy of mathematics, which became important in the 20th century and affected math education.

Would this help guide me to understand what might be "inefficient" or strange or shortcuts?
