Lattice Multiplication is a structured method of multiplying numbers using a grid and diagonals. It helps learners organize their work clearly, reduce common multiplication errors, and accurately multiply large numbers. The method is especially useful for multi-digit multiplication and supports learners who struggle with traditional long multiplication.
