What is estimation in maths?
To make calculations easier, estimation is a rough calculation of the actual value, number, or amount. When we employ estimated values in a calculation to produce an approximate, projected result rather than an exact result, we are using estimation. Using round numbers in estimations helps to make computations easier to understand.
In terms of estimation, 10,320 would be estimated as 10,000 when rounded to the closest thousand.
