And never will. Or even earlier, that slope of a
non-horizontal, non-vertical 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

who never will. The "Math-Teach", the name of
this listserve, really does have meaning along with "mathematics" itself.
