The author proposes a new mental arithmetic operation, denoted as ⊞ (squared plus), to simplify calculations involving the Pythagorean theorem and similar additive variance principles. This operation combines squaring, adding, and taking the square root into a single, more intuitive step. While an IBM paper from the 1980s offered a computational method, the author highlights a human-friendly estimation technique called alpha-max plus beta-min, which provides results within 3% error.
