...math (in the sort of "doing stuff with functions in (R -> R), or multiplications/division")

This is not what math is. It's more what calculus is and math is a lot more than calculus. Most mathematics is not about numbers at all.

BTW: Interesting results about sorting algorithms (e.g. the lower bound of O(nlogn) complexity for comparison-based sorts) require maths (specifically combinatorics, permutations etc). Concurrency involves math, too. See the famous happens-before relationship which involves notions of sets (of executions), transitivity, partial ordering, etc.

[OT] What's the probability of two comments with very similar views appearing at the same time :-). I too did comment almost exactly same thing!
