It might not prove him stupid (though my guess is you could find adjectives that are less fitting), but it does prove that he never understood the math. A concurrent post mentioned forgetting whether slope is rise/run or run/rise. That kind of thing is what you can forget. If you're "forgetting" the basic rules of algebra and can't recover them with a few moments of thought, then you're doing it wrong.
- ebrenes 15y agoI'm willing to accept someone was careless if they mix up rise/run or run/rise. But you can readily summon the correct expression if you understand what slope means algebraically/geometrically. So barring a sloppy mistake, which we all have, it's just as indicative of lacking proper geometric understanding. For example, a basic linear equation y = m*x would readily yield that m being the slope is m = y/x, so it's rise over run. That's one of the things I always treasured about math, that you could work out the formulas if you didn't care to memorize them.
