Writing in math, how can estimating help you add two-digit numbers?

Answer 1

If you estimate the sum, you have a general idea of your answer. If your actual answer isn't close to the estimate, you know you need to add the numbers again.

Estimating is also useful when you need an approximate answer and it's not convenient to use a calculator or pencil and paper to get the exact answer.
