Uses of Estimation of Numbers
Estimation of numbers is the process of estimating/approximating or rounding off the numbers in which the value is used for some other purpose in order to avoid the complicated calculations. There is a difference between the term exact and the estimation.
In mathematics, the term ‘exact’ refers to ‘equal’ and the ‘estimation’ refers to the ‘approximated’ value. Estimation of numbers saves the times. After estimating the numbers, we don’t require calculators to solve the problem. But in mathematics, we always require an exact answer. Estimation is the process of finding the number which is close enough to the exact solution. But it is not an exact answer.
In real life, for instance, there were around 500 people present in the marriage hall. Hence, it is an approximate figure and the actual number.
