Estimating and Rounding

The video tutorial covers the basics of estimating and rounding numbers. It explains how to round numbers to the nearest ten, hundred, and thousand using practical examples. The key concept is to identify the digit to round and determine whether to round up or leave it as is, based on the digit immediately following it. The tutorial emphasizes clearing out digits behind the rounded number and provides a simple rule: if the digit is 5 or higher, round up; if it's 4 or lower, leave it unchanged.
