Reading the Odometer (Rounding Large Whole Numbers to the Nearest Ten with a Carry)

The video tutorial explains how an odometer works by counting miles and resetting digits. It then draws a parallel to rounding numbers to the nearest ten, especially when multiple digits need to be adjusted. Through examples, it demonstrates how to handle carries when rounding numbers like 72,999 and 199,995, emphasizing the process of adjusting digits and carrying over values. The lesson concludes with a summary of rounding multi-digit numbers when carries are involved.
