I do not know (he's lying--Yahoo site statistics tell all) how many of
you reached this "slide":
http://www.theoryyalgebra.com/demo-15.html
I hope I do not get sued too badly for using that sound clip, but can
they blame me?
Anyway, there was a Great Lisp Moment related to that functionality. A
terribly influential math education bigwig who just happens also to run
the secondary math department for a big US city snuck into the booth
incognito. He stood in the second row talking to my bro while I gave the
demo to someone else.
When I was done, I got up to see what was going on. The guy was just
talking about how /he/ taught and showed no interest in the software. He
said he had kids play with equations.
Hunh?
Like x = 5.
That's the answer.
Right, then change it to 3x=15.
Oh. Cool.
But it was a pity he had no interest in the software. Not that I knew
who he was, just that he was missing out on some good software.
Then I remembered this slide. Sat down, warned him the tutor would be
dubious at each step, then executed his methodology, unsolving my demo:
x < -5
x < 15/-3
-3x > 15
-3x - 2 > 13
He took my card, wrote his work number on the back, and told us who he
was (well, I asked him exactly who he was when some things he said
suggested he was bigger than he was letting on.)
Great fun, and a perfect demonstration of the value of Tilton's Law:
Always move towards the light.
