It’s really hard to understand some of it. It might’ve been fun if I had good math instructors for every class at every step of the way from algebra to ordinary differentials. Because so much material builds on what was taught before, it gradually got more and more incomprehensible until I gave up trying to understand it halfway through cal 2 and just memorized the important parts enough to pass. Besides that, I rarely see applications in day to day life past basic algebra. It’s not like I’m gonna take careful measurements of how fast my car’s going to derive my exact fuel consumption rate. It’s easier to just go off the odometer and gas pump readings between fills for instance.
