How to Multiply Using Lines for Big Numbers and Zeros

TL;DR

To multiply big numbers and handle zeros using lines, draw intersecting lines corresponding to each digit for both numbers. Count the intersection points to find the product, where different colors can denote zeros and larger digits, making the process visually manageable and intuitive.
