Scientific computing combines mathematics, programming, and domain knowledge to solve complex real-world problems in physics, biology, engineering, and beyond — usually where an exact pen-and-paper solution isn't practical.
1-A 2-A 3-A 4-A | 5 programming 6 simulation 7 = Mathematics, programming and domain-specific knowledge 8 = It approximates behaviour when exact solutions aren't feasible 9 = Finding maxima/minima of complex functions | 10 = Floating-point rounding makes small errors unavoidable
