Explanation Given Information: The provided numbers are 9823 + 7516 + 8205 . Formula used: Steps to add whole numbers: Step 1: Round off the each addends to the first digit and then add them to estimate the sum. Step 2: Calculate the exact sum. Step 3: Now compare the obtained estimated sum with exact sum and identify whether the exact sum is reasonable. Step 4: Again add the number second time to check the exact sum. Calculation: Consider the provided numbers 9823 + 7516 + 8205 . Round off the each addend to the first digit as shown below: 10000 + 8000 + 8000 N
