How do you estimate the sum of 202 and 57?
One number is about 200, the other is about 60.
The sum will be about 260.
You consider the term "about" to be an estimate.
Saying "It will take about 2 and a half hours to get there" (instead of "2 hours 24 minutes and 30 seconds") would be appropriate if you were traveling.
The party drew roughly fifty attendees.
In this instance, we are adding two numbers: approximately 200 and 60.
It will come to roughly 260.
It would be reasonable to estimate the number of attendees at a meeting to the nearest 10, but that would not be reasonable for the number of attendees at a soccer match or music festival. The amount of rounding depends on the size of the numbers and how accurate you need to be.
It's possible that you'll be asked to estimate and then round to the nearest whole number, one significant figure, or the appropriate degree of accuracy.
Estimation is a helpful skill, and it is beneficial to estimate a calculation's answer beforehand.
You will be able to tell there's a problem if your actual response differs significantly.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
