First picture is a photo I found floating on Facebook. Second picture is my reasoning.
Some of you know that I teach physics. In class I always teach the importance of having UNITS accompanying your numbers and knowing your unit conversions, but none of my students ever gave a shit about it. Every week I would remind them this and every week most of them would still not put down units. Well, this is the reason units are important: your boss might one of those assholes who can’t do math correctly, yet they act like they know their shit.
