For example, in law or philosophy, repeating the same argument multiple times, adapted for different circumstances, can give it weight. In math and programming, the weight of repetition is dead weight that people strive to eliminate. In law and philosophy, arguments are built out of words and shared assumptions that change over time; in math, new definitions can be added, and terms can be confusingly overloaded, but old definitions remain accessible in a way that old cultural assumptions are not accessible to someone writing a legal argument.
In physics, the real world is a given, and we approximate it as best we can. In math and software, reality is chosen from the systems we are able to construct. Think of all the things in our society that would be different if they were not constrained by our ability to construct software. Traffic, for one — there would be no human drivers and almost zero traffic deaths.
Where programming differs from math is that math is limited only by human constraints. Running programs on real hardware imposes additional constraints that interact with the human ones.
