Question

Answer the following in detail.

When are approximations necessary in daily life and when should they be avoided?

Answer in Brief

Solution

An approximation or estimation is a reasonable guess about the measure of a physical quantity. For example, we use an approximation in adding salt to food while cooking. We use approximation when we try to figure out the time it would take to reach a certain place by car. In our daily life, we use approximations in many situations. They are useful as they save time. But, since they are not accurate in measurements, they should be avoided in scientific studies and experimentation.
