Transcript text: Estimate each sum or difference by $562+814 \quad 937-486$

Solution

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:

Step 2: Estimate the Sum

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

Step 3: Estimate the Difference

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

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