Okay so let me give you a background of my mathematical education.
I didn’t really have one.
Somehow I have managed to pass all of my remedial math classes without knowing my times table (yea 8x7 = i have no fucking idea)
I never learned square roots, my math teacher like sophomore, junior year or whatever was like “Uhh well square roots are hard and you’ll never really need them so were just gonna skip this”
So that doo-hickey above makes no more sense to me than a cave drawing.
(Actually a cave drawing would make a lot more sense to me.)
