Lattice, or sieve, multiplication is algorithmically equivalent to long multiplication. It requires the preparation of a lattice (a grid drawn on paper) which guides the calculation and separates all the multiplications from the additions. It was introduced to Europe in 1202 in Fibonacci's Liber Abaci. Leonardo described the operation as mental, using his right and left hands to carry the intermediate calculations. Matrakçı Nasuh presented 6 different variances of this method in this 16th century book, Umdet-ul Hisab. It was widely used in Enderun schools across the Ottoman Empire.[3] Napier's bones, or Napier's rods also used this method, as published by Napier in 1617, the year of his death.
