I think for this discussion, "math is stuff you'd learn in a math department" is a pretty useful definition, even if it's not a very good one. There's a lot of math involved in the design and manufacture of the kettle, electrical grid, and water utilities, but a person's ability to put a kettle on isn't going to be improved by math classes. In that way, programming probably is a bit mathy, but good programming is more like good technical writing than it is like math.

That means that definition shifts over time. For example, courses on numerical analysis, graph algorithms, programming, and on compilers used to be part of “what you’d learn in a math department”.
It likely also even today will show geographical variation.
