Baldi's basics is actually way more mathematical than one is led to think: unless you develop some sick strategy to collect the notebooks, you're doomed. Those baby math questions in notebooks are there just to show you how lame a math teacher Baldi really is.
Student : Why do we study maths ???
Teacher : Mathematicssaves lives .
Student : How is that ?
Teacher : It keeps stupid people like you from getting to medical school .
Math is like an STD, it starts out as just a pain, but then it festers into this horrible disease which you can't even understand let alone do anything about.
A) Elementary School: This adding shit is easy, but annoying as fuck
B) Middle School: Ugh equations n shit, man this is so much worse than elementary school
c) High School: Fuck man, all this trigonometry, sin cos bullshit, polar coordinates and shit, this pretty hard
d) College: WTF, FUCK THIS STUPID CALCULUS FINDING THE THIRD INTEGRAL OF A IMPLICIT FUNCTION FUCK THAT I DON'T GET SHIT FUCK
e) Advanced College: MAN I THOUGHT CALC WAS BAD, FUCK THIS LINEAR ALGEBRA, VECTORS IN THE 8th DIMENSION SHIT MAN, AT LEAST CALC I COULDS SEE WHAT THE FUCK I WAS DOING, NOW I'm JUST FUCK A NUMBER IN THE ASS AND THEN SOMEHOW FIGURING OUT SOME OTHER GAY SHIT
d) Graduate School and Beyond: This theoretical physics man... this ain't even math.. all I'm doing is making up some shit, using a couple numbers and getting paid, if only I had known math was going to be this easy before.
The act of preforming mathematics (shortened word: math)
Person #1: "Shhh! Hold on, I'm mathing!!"
Person #2: *confused*
Person #2: "Don't you mean you're doing math!?"
Person #1: "NO!! I'm mathing, so shut up so I can figure this out!!"
Person #2: "Wow, okay then..."
Person #1: "Thanks, now I need to math all over again because you interrupted me! Ugh!!"
Person #2: "But it's simple math, you'll live!"
Person #1: "But mathing is hard!!"
Basically it's used when the person preforming the act of mathematics has an already difficult time doing simple math, making them frustrated and forcing them to explain why "mathing is hard, yo!"
