Why is estimating an important skill in your real life?

Answer 1

Frequently, it is either impossible to obtain exact answers or too expensive

to do so. An air conditioning salesperson preparing a bid would be wasting time and money by measuring rooms exactly. Astronomers attempting to determine movements of celestial objects cannot obtain precise measurements. Many people use approximations because it is easier than using exact numbers. Shoppers, for example, use approximations to determine whether they have sufficient funds to purchase items. Travelers use rough estimates of time, distance, and cost when planning trips. Commonly reported data often use levels of precision which have been accepted as appropriate, even though they may not be considered "exact." Astronomers usually report information to two significant digits, and batting averages for Baseball players are always reported as three-place decimals
