{wiki=Littlewood's_three_principles_of_real_analysis}
Littlewood's three principles of real analysis, proposed by mathematician J.E. Littlewood, are informal but powerful heuristics that can guide the understanding and analysis of real functions and sequences. Though they are not formal theorems, they serve as useful guidelines for approaching problems in real analysis.
