Rounding Whole Numbers Concepts

The video tutorial explains how to round whole numbers to the nearest 10 using both a number line and formal rules. It provides examples with numbers like 677, 243, 755, and 498, demonstrating the process of rounding up or down based on proximity to the nearest 10. Special cases, such as when a number is equidistant between two tens, are also covered, with the rule to always round up in such scenarios.
