Type:
OtherDescription:
Leonardo Fibonacci's multiplication algorithm arrays the digits of multiplicands along a rectangular lattice. Read an explanation of the technique, see a few worked examples, and watch the method in action with a Java applet. Clicking a little off-center of any digit of a multiplicand (left to increase, right to decrease) instantly changes resulting products and sums throughout the lattice.
