As an electrical engineer, I like to quip that 99% of the work I do requires only V=IR, or slight variations / derivations thereof. Of course, it's that remaining 1% that will fuck you if you don't have the maths chops. And this is as a consulting engineer, which arguably uses the least maths. Once you get into actual design or analysis, that number becomes a sliding scale in the other direction very quickly.
