The hard part of electrical engineering was never the mathematics — it is knowing what the mathematics is entitled to claim. Every formula was applied correctly, and the answer is still wrong. Most introductory books present equations as facts and problems as exercises in substitution. Readers finish able to compute a node voltage but unable to say which assumptions the result rests on, whether its magnitude is even plausible, or what it implies for a real component on a real bench.
