90% of programming I have seen after a decade plus of doing it full time is minor changes being made to code that was already made by someone. Likely not documented. Likely already changed in a dozen little ways. Math isn’t the problem. Understanding what the guy who wrote it is often the problem.
Oh and you can’t ask them because they likely don’t work here anymore.
Being a programmer is more like being a detective than anything else unless you work for a small company.
