And never will. Or even earlier, that slope of a nonhorizontal, nonvertical line on that grid has something to do with similar triangles. So what? That's no excuse for not teaching things in logical order for those who do and impeding their progress for the "good" of those student who never will. The "MathTeach", the name of this listserve, really does have meaning along with "mathematics" itself.
