Why do we use estimated sum?

The key with estimation is to only use it in instances that don’t require an exact answer.

You can estimate sums (the answers to addition problems), and differences (the answers to subtraction problems).

When solving a math problem, we can check if the answer we have derived to is reasonable or not, based on an estimate. A reasonable estimate does not exceed the original numbers in a problem. … Since 96 (actual answer) ≈ 90 (estimate answer), we know our solution is correct.

How do you determine reasonableness?

Subtract the smaller number from the larger one to check for reasonableness. In this example, you would subtract 600 from 651 to get 51. The numbers are reasonably close, so you can probably accept that 651 is the correct answer.
