1010 words this morning, which brings "Periastron" 2037 words, counting outline notes. Basically, it's just an excuse for a huge gonzo space battle, but even that requires a little setup. And a planet where it rains pellets of molten iron is just the place to set the scene.

My word count for the year so far: 91,315. I am doing *so* much better than last year.

372.6 miles to Rivendell.

I suspect this algebra book I am using* (Practical Algebra: A Self-Teaching Guide, Selby and Slavin) was written by people with a serious gift for getting their point across. Because I am actually understanding everything they're getting at, on a theoretical level.

I still can't do arithmetic to save my life, but that's where the dyscalculia kicks in, I guess. Fortunately, since I am not actually attempting to pass tests or doing homework I am graded on, when I get something wrong because of a stupid multiplication error, I can go back and figure out what went wrong and fix it. I wonder if I would have had more success learning this stuff in high school if the grading process had been less based on getting the right answer and more based on understanding the process. I suspect it would have: I got high Bs in physics.

Math, well. Let's just say that a passing grade at my school was 70%. And I... passed.

Mostly, I suspect, out of teacher pity.

Anyway, this chapter is positive and negative numbers. I remember more of this than I thought I would. And the processes make perfect sense.

I wish I always got the same answer for 2x3, though. That's embarrassing.

Well, off to get cleaned up and dressed and eat something and practice guitar. Because we do more in our pajamas by lunchtime than most people do in their pants, all day. *g* Er. So to speak.


*In conjunction with the Algebra Workbook for Dummies, which I like much much less.

How do *I* use zinc oxide in *my* daily life?

Kentucky Fried Movie! I haven't seen that in years.

Winamp kicked up the sound file this morning between other stuff, and I laughed and laughed.*

For some of us, comprehending algebra can happen somewhere after thirty five. At least, this happened to me when I found myself having to tutor a tenth grader, which meant I had to teach myself the math that I had flunked three times in high school. I used the Saxon home schooling method, but I suspect most modern math books will be able to teach you--if your brain has decided it's ready to learn it. I told myself, if a fifteen year old can do it, I can: and I worked my way steadily up to Algebra two, despite having to rework problems over and over (sometimes unnecessarily because I'd reversed numbers).
good for you!
My father had a great-aunt who never mastered the multiplication table. She and her husband kept a country store, and she had a copy of the multiplication table hidden under the counter, so she could figure out what 10 pounds of flour at X cents a pound came to. It's not an elegant solution, but it's a solution.

I wonder how you'd do with an abacus? Because that's got lots of lovely kinesthesia built in.
I have multiplication table hacks, which I figured out in third grade, because I could not memorize the fucking thing.

The problem is not that I don't *know* that 3x2 is 6. It's that I will look at 3x2 and see a problem to which the solution is "8". And I *know* it's 8, with the arithmatic-performing portion of my brain. Which, even though it's looking at the numbers 3x2, is *seeing* 2x4, or something.

I will make these errors even with a multiplication table, or a calculator. Even though I know intellectually, even visually and verbally, that if I take two sets of three, the result is six, when I carry out the process, what I get is 8.

It's a **wiring problem,** like dyslexia. I'm pretty sure an abacus won't help.

*notes title*

I only ever had one teacher who could explain complicated math to me in ways that made sense -- another predominantly-lefty. For some reason I could do multiplication tables -- it's simple addition I have hacks for. Never found a hack for word problems that worked. Thank goodness real world word problems are much easier to understand.

I never took Physics, even though I was taking other college-track classes. Physics is all word problems, from what I can tell.

A friend of mine is a graduate student in math, from Japan. I'm giving him a ride to judo, and he's doing these complex calculations in his head as we're driving along. I said, "Here, at least scribble on a napkin. Please. You'll make me feel so much better."
Because of *you*, one of these days soon I'm going to have to nail down this "calculus" thing. Right after I've got the reading-the-Hebrew-alphabet thing sorted out.
And I wish I wouldn't drop important words out of sentences and/or replaces them with near homonyms and inconvenient moments. And then not notice until 10 minutes later, when it's too late to change what I've written. I guess we have to live with it, and move on.

(Except when we can't, because it gives us the twitchies.)
see, case in point: "and/or replace them with near homonyms at inconvenient moments."

*twitches angrily*
I must have missed something. Why are you studying algebra?
Because I don't know it!
hey, if it helps, there are three types of basic algebra problems -

- farmer problems (how much fence do you need, how big is your field,etc.)

- volume/dispersion problems (how much of which chemical did you use in your concoction)

- distance/rate/time problems

...and each type has its own set of steps for solution. Recognizing the type is the hard part.

Good luck!
Heee! How did you *know*?

I excel at math. That's what my undergrad degree was in.

But I *still* need to check any problems involving the numbers 2 and 3. Because somehow, my brain is determined to randomly switch 2x3 and 2+3 for no known reason, apparently whether the little cross between the numbers is standing balanced on one leg or two does not register with the brain. And I don't have that problem with any OTHER numbers. Just those.

Brains are weird.
brains are really weird.
Yay, more Cat and Monkey!
My last math teacher's pet silly mistake was 2+3=6. She warned us at the start of the year and sure enough throughout the year every now and then we'd catch her in it. (If she'd been really sneaky she'd have invented it as a way of making us pay attention and/or teaching us that even experts make mistakes. But I knew her well enough that I'm almost 100% certain it was genuine.)
Basically, it's just an excuse for a huge gonzo space battle

Who needs an excuse?

The narrative!
I'm with you on this one, Bear. I pick up a calculator to find out 2x3, and get it wrong the first time anyway. One of the big benefits that knitting brings me is that it forces me to practice arithmetic on a daily basis. Some days I can even manage it without counting on my fingers.

There is nothing sadder than the cat looking at you funny because you are counting on your finger OUT LOUD.

::sighs::
LOL!

Your cat and my cat should do lunch....
