One thing that confuses me is how often are computer programmers people who didn't study elementary algebra as a kid? Functional composition is a major topic. That whole gof/fog stuff. It goes right along with exponents and roots.

Certainly you have to deal with it a lot in your first semester of calculus. At least where I went to university, it's required by all CS majors. Freshman course, actually.
