# About This Calculator
Lattice Multiplication is a method that breaks long multiplication into smaller steps using a grid.
Each cell contains the product of a row and column digit, split diagonally into tens (top-left) and ones (bottom-right). The final answer is found by summing the numbers along the diagonal "channels".
