Multiplication Using Visual Models (Part 2)

The video tutorial explains how to use rectangular arrays to simplify multiplication of one-digit numbers and numbers with trailing zeros. By representing numbers with lines or shapes in arrays, the process of counting becomes easier. Examples include multiplying 3 and 10, 4 and 30, 4 and 200, and 5 and 2000, demonstrating how to handle zeros efficiently.
