12/1/2023 0 Comments Lattice method example![]() Notice that there are no carries in the addition otherwise, this method would not appear to as great an advantage. The lattice lines are drawn so as to visually facilitate this, but otherwise, there's nothing terribly magical going on here. Secondly, we leave all the carries unevaluated at first, so that instead of writing $5100$, we write $^10^25^25$: Well, this is the same thing, except that first of all, we reverse the rows, so that we multiply $255 \times 20$ first. The first row would have the result of multiplying $255 \times 5$, which is $1275$, and the second row would have the result of multiplying $255 \times 20$, which is $5100$. ![]() That is, imagine multiplying $255 \times 25$ the usual way. (1982), Exactly solved models in statistical mechanics (PDF), London: Academic Press Inc.This is really just ordinary long multiplication, but with lazy evaluation of carries, and the rows are inverted. ![]()
