The universal truth of mathematics: spending 3 hours on a complex differential equation only to realize you wrote 5+7=13 somewhere on page one. That massive 55% yellow slice isn't just a statistic—it's my biography.
Ever notice how your brain can simultaneously calculate the trajectory of a falling coffee cup but somehow forget that negative signs exist? That's the 26% gray slice working its magic.
The real kicker? Only 4% of errors come from not understanding the problem. Turns out we're all geniuses trapped in bodies that can't do elementary school arithmetic!
