What is rounding?
Rounding numbers mean adjusting the value of a number(up or down) to make calculations easier and simpler. The answers given by the rounded numbers are not accurate and precise but close to its value.

Rounding Rules:
In the whole numbers, start by looking at the place value of the digit. Next, look at the digit on the right side of your rounding number.
-
- If the number is between 1-4, then, you don’t change the rounding number. Only the numbers on the right side turn to zero.
Example: 449 becomes 400 when rounded to the nearest hundreds.
-
- If the number is between 5 -9, then, you add 1 to the rounding number and the numbers on right turn to zero.
Example: 7741 becomes 8000 when rounded to nearest thousands.
