I would add some nuance, to make the list look more like: 1A) Ability to create new mathematical ways of talking about your systems. This means things like inventing new notations, conventions, or combinations of mathematical methods from disparate mathematical disciplines. 1B) Ability to recognize when a mathematical finding applies to your system. You may not be able to come up with it on your own, but you know it when you see it. 2) Ability to implement conventional methods quickly to your problem, even a complex one.
