Estimation
Finding a value that is close enough to the right answer, usually with some thought or calculation involved.
Example: Rahul's estimation of 150 bricks to build a wall was very good as they were only 5 bricks left.
Estimation only finds the approximate value which is a value close to the actual value.
This method is commonly used to round off the numbers nearest to tens, hundreds, thousands and so on..... Estimating sum, difference, product and quotient
