The Japanese multiplication method, also known as the lattice or line method, is a visual technique for multiplying numbers using intersecting lines. Instead of traditional multiplication tables, this method represents each digit of the numbers as sets of parallel lines. The intersections of these lines are counted and grouped to form the final result. This approach is popular because it transforms multiplication into a clear, geometric process, making it easier for visual learners to understand
