Reminds me of an experience with my oldest
nephew, 6 or 7, while I was a senior in
college. We had a nice discussion one evening
about temperatures because we were in Iowa and
having "below zero" weather using a number line
comparison with a thermometer scale. As luck
would have it, my younger sister was preparing to
teach elementary school and observing Larry's
classroom. The teacher was quizzing them on
number facts and accidentally said "4 minus 9"
instead of "9 minus 4" and Larry chimed right in
with, "Negative 5" or possibly "Minus 5". I
can't remember if the flustered teacher
acknowledged correctness or not before saying
"Oh, I meant to say" Such things, elementary
algebra included, are only hard if they are made hard.
