tom lehrer is 90????
his song "new math" never made much sense to me because i'm pretty sure what he describes is the same way they teach us here (and i don't think our math education ever changed)
@squirrel "The New Math" was a thing that happened in USA in the 60s.

@rainwarrior i know that, i just mean the example in tom lehrer's song made sense to me
or at least, i remember so, it was a long time ago since i heard the song
@squirrel I just listened to the song, had never heard it before.
I think the "new math" part is just the base 8 thing?
@squirrel Oh I guess there was kind of a change in the standard way to describe subtraction/borrowing, but that part actually stuck around (unlike teaching bases)?
@squirrel This version has an animation that kinda shows the difference:

And on Wikipedia it's "Austrian" vs "American" method:

@rainwarrior yeah i use the one Wikipedia calls American method
