I wish I could argue against this... but we are operating in a hobby where even people who are deeply invested, have been playing for a long time, and play in multiple widely divergent systems can say with a straight face "subtraction is significantly more difficult than addition" and everyone around will nod along, not only taking it seriously, but as gospel. At this point, I wouldn't be surprised if making a new version of D&D where you don't need to take off your shoes to do the math took the gaming world by storm.
