This video tutorial demonstrates a simple method for multiplying numbers that end in zeros. The instructor explains how to handle trailing zeros by temporarily setting them aside, performing the multiplication on the remaining numbers, and then reattaching the zeros to the result. The tutorial includes four examples: multiplying 300 by 50, 8000 by 1200, 2400 by 7000, and 532 by 110000. Each example is broken down step-by-step to illustrate the process clearly.
