Lattice Multiplication Method

This tool allows users to explore the lattice method of multiplication. The tool is restricted to one factor from 0 to 99 and the second factor from 0 to 18. Users can turn on and off the sliders for the factor values, the grid (box), the values in the box, and the answer shown separately.
