Watch me teach a very basic math problem.

The whole thing makes me self-conscious.

I followed every step of that, up to the last stage, which I didn't follow merely because it was something I hadn't been taught and I'm not good with math.

I told you once that I didn't follow math because I'd been told that I wasn't supposed to. because I was a girl? I don't think that's technically true: I was just taught it by bad teachers (i.e., my mother's boyfriend when I was still in kindergarten, yeah, I know it's nuts, but the sonofabitch made me cry and I was just three, you know?)

This isn't something I *can't* learn, it's just something I haven't learned, and I don't see a screaming need to learn it in the near future.

There are a lot of cultural things that go into our horrible, horrible math education. And yeah, I can completely understand that if you had a punishing bastard as a teacher early on you would never see any interest in going any farther. And the whole thing is a shame, because math and logic are such great ways to teach each other. You don't need math to get at logic, but it saves you a hell of a lot of work if you have some intuition from geometry.

But it's good to know that what I worked out was clear. The whole thing still makes me self-conscious. I recorded 20 of those today, and there was a lot of taping oer myself as I made mistakes, over expalined, under explained and the like.

hmm... I spent the video watching your hands. I wonder can you wear nail polish?

Did my unpolished hands gross you out? I actually had a fight with my co-worker about colloquialisms in these things. She was unhappy with me calling terms 'suckers', for example. Nail paint or clever messages on my hands would likely cause conflict.

plus it's not one over th exponent it's one over the base dear ;)

Ya got me. But I did the math right, at least :)

I think I'd have a massive tendency to under explain. I looked at it and my brain just -- DID it. The step with treating the fourth power as the square of a square? I know fourth powers of very small integers cold, and forget squaring the square as needed.

That was good.

Oh, believe me, I understand. And if you'll believe it, the criticism I got from admin was that I was talking too fast and skipping too many steps. Like I should have justified the step of squaring the square, rather than assuming that they new that property of exponents.

Also, in a total non sequitir, we are having people over tomorrow (and most Fridays) around 7. It's going to be a casual wine and dinner. You are more than welcome. :)
