More Math Meta (or is that Meta Math?)
In this thread, where people share their thinking while doing an addition problem, @athelind posted a video of the Tom Lehrer’s “New Math.” The second verse of that song is all about Base Eight.
And that reminded me that I’ve now been (semi)converted into base 12, at least for some things. I kinda mix it up between base ten and base 12, depending on what I’m trying to figure out.
And here’s the video that converted me (sorta):
(As he explains at the end of the video, I count the segments of my fingers on my right hand, using my thumb as a ‘pointer.’ I’m not as dexterous with my left hand, so I just count one to five as “normal” with that hand, to keep track of how many units of do I’ve got to. So I can count to 60 on the fingers of two hands)
Oh, and I also learned to count in American Sign Language, back before I hit puberty (when language/math stuff comes more easily). And ASL is sorta like a hybrid between base 5 and base 10:
(I use ASL numbers when I want to count things, while listing them aloud in English)
