Math is not just arithmetic. Arithmetic is a subset of math. There are a lot of subsets. Linear math, non-linear math, logic, sets, (as the King of Siam was fond of saying) etc, etc. We got exposed to lots of the subsets in public school.* Most of the program logic on our desktops doesn't go beyond obvious math subsets. Neither does most of the code we develop.* Keep in mind our programs have to talk to some fairly ignorant hardware.* Some of the programming we do translates very high level math concepts (think Wolfram, ...) into programs that our ignorant hardware will understand. Some of it is a lot simpler. All of it depends on at least the logic subset of math. * Rant opportunity
