There’s a discussion over at Slashdot on how to learn/relearn math. As with all Slashdot discussions, the comments run the gamut from informative to a waste of electrons. Since I’m all about the continuing education, I found some of the advice and linkage to be interesting and (potentially) useful.
It’s also interesting to consider the effects of calculators and smart cash registers on arithmetic skills in the same light that other technology may have effected memory (the link referring to the “outboard brain”).
Just remember the advice (which I’ve seen on t-shirts and bumper stickers) posted by one commenter: Don’t drink and derive.
