What is estimation? When is it helpful to use estimation?

Short Answer

Expert verified
Estimation is a method of approximate calculation, often involving rounding, which is useful in many real-life situations where precise figures aren't necessary or when quick calculations need to be made.

Step by step solution

01

Define Estimation

Estimation is a mathematical strategy used to approximate a quantity without counting or measuring it exactly. This approximation often involves rounding or other simplifications to make calculations easier.
02

Explain the Usefulness of Estimation

Estimation is extremely useful in a variety of situations, particularly when needing to make quick calculations where the exact number is not necessary. This could include everyday situations such as estimating the time it will take to travel somewhere, estimating the total price of items in a shopping cart, or determining if you have enough money to make a purchase. It's also helpful when the measurement tools are not precise or when an ballpark figure is all that's required to make a decision.
