Solution Steps

To estimate the sum or difference, we can round each number to the nearest hundred and then perform the arithmetic operation.

Step 1: Round the Numbers to the Nearest Hundred

We start by rounding each number to the nearest hundred:

  • 562 562 rounds to 600 600
  • 814 814 rounds to 800 800
  • 937 937 rounds to 900 900
  • 486 486 rounds to 500 500
Step 2: Estimate the Sum

Next, we estimate the sum of 562 562 and 814 814 by adding their rounded values: 600+800=1400 600 + 800 = 1400

Step 3: Estimate the Difference

Then, we estimate the difference between 937 937 and 486 486 by subtracting their rounded values: 900500=400 900 - 500 = 400

Final Answer

The estimated sum is: 1400 \boxed{1400} The estimated difference is: 400 \boxed{400}
