Rounding Numbers to the Nearest Tens

The video tutorial explains how to round numbers to the nearest tens place using three examples: 57, 83, and 25. It covers both graphical methods and formal rounding rules. The tutorial highlights the importance of identifying the tens place and the digit to the right to determine whether to round up or down. Special attention is given to numbers that are exactly in the middle, like 25, which are rounded up according to standard rules.
