In this video students learn to round a number to a given place using the following steps. First, find the digit in the rounding place. Next, look at the digit to the right of the rounding place. If the digit to the right of the rounding place is les...s than 5, round down, which means that the digit in the rounding place stays the same, and all digits to the right of the place become zero. If the digit to the right of the rounding place is 5 or greater, round up, which means add 1 to the digit in the rounding place, and all digits to the right of the rounding place become zero.
