Estimating Products and Rounding

The video tutorial explains how to estimate decimal products by rounding numbers to the nearest whole number. It covers three examples: estimating 3.2 * 2.8, 7.6 * 11.2, and 0.13 * 7.4. The process involves rounding each decimal to the nearest whole number and then multiplying the rounded numbers to get an approximate product. The tutorial emphasizes the importance of understanding when to round up or down based on the decimal value.
