{wiki=Toom–Cook_multiplication}

Toom-Cook multiplication is an algorithm designed for multiplying large integers that is more efficient than the traditional grade-school multiplication method. It is based on a divide-and-conquer approach that reduces the number of multiplicative operations required. The primary idea of Toom-Cook multiplication is to recursively divide each of the numbers to be multiplied into smaller parts, perform several smaller multiplications, and then combine the results using interpolation.
