i mean like a specific formalism (ideally one that can fade into the background once learned) the dual numbers are a good example, you just make up a number e such that e * e = 0 then you can differentiate f(x) by just evaluating (f(x+e)-f(x))/e (fun thing to try out)

another "system" would be non-standard analysis this is where you pretend there's a number H that's like infinity but still a natural number, and then you can use 1/H as your infinitesimal this one makes integrals nice, since you're just adding up H slices of width 1/H
