My diffeq professor explained it as the fifth form of arithmetic (first four being addition, subtraction, multiplication, and division). This fifth form is unique because you sweep two functions relative to time and each other. To be honest, I still don't fully grasp the concept and I just use it as a mathematical tool. I need a 3blue1brown video to explain this to me so I can have an "aha!" moment like I had in his linear algebra videos.
