The way most people learn to multiply large numbers looks something like this: 86 x 57 ------ 602 + 4300 ------ 4902If you know your multiplication facts, this "long multiplication" is quick and relatively simple. However, there are many other ways to multiply. One of these methods is often called the Russian peasant algorithm. You don't need multiplication facts to use the Russian peasant algor..
