Lattice multiplication is a method of multiplication that uses a lattice to multiply two multi-digit numbers. It is similar to regular long multiplication, but it breaks the process into simple multiplications followed by simple additions. This is similar to box multiplication. Note that each cell is magnified in the center of the screen as well as showing up in a multiplication table. Also note that the Trachtenberg system is followed under the Step Column by Column sequence. If the sum of the column results in a two digit number, then you will need to carry the tens. Note that the carry digits are in red. For hardcopy, after you click Get Lattice Table then right click on the Flash window to print out exercise sheets, and then choose Print...
