The passage around this formula
Here is where a structural audit earns its keep instead of restating the press release, because the announcement’s own supporting table contains the seed of the correction. DeepMind’s paper states that for three of its results — including the 4×4 case — “the algorithms discovered by AlphaEvolve use complex-valued multiplications which can be used for exact multiplication of complex or real-valued matrices” [ 2 ] . That sentence is true and also incomplete in a way that matters enormously for anyone trying to actually use the result. A complex-valued multiplication is not one hardware operation; multiplying two complex numbers (a+bi)(c+di) by the direct method costs four real multiplications,…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
