An artificial-intelligence approach known as AlphaTensor found exact matrix-multiplication algorithms that are more efficient than those previously known for many matrix sizes.

DeepMind breaks 50-year math record using AI; new record falls a week later AlphaTensor discovers better algorithms for matrix math, inspiring another improvement from afar.

Even for computers, the long multiplication algorithm, defined as n to the power of, could reportedly take months if each number had a billion digits.

AI engineers develop an algorithm that will replace floating-point multiplication with integer addition to make AI processing more efficient.

While the box method is essentially the same as the standard algorithm, it does a much nicer job of illustrating what's going on in a multiple-digit multiplication problem. 23 times 7 really just ...
