How do you do a lattice multiplication?

  1. Draw a table with a x b number of columns and rows, respectively.
  2. Align the digits of the multiplicand with the columns and place it on top of the table.
  3. Create a diagonal path for the tables.
  4. Multiply the numbers using the distributive method.
  5. Start adding the numbers on the same diagonal paths.

What is a partial sum addition?
