Questions: Estimate each sum or difference by 562+814 937-486

Solution Steps

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

We start by rounding each number to the nearest hundred:

• $562$ rounds to $600$
• $814$ rounds to $800$
• $937$ rounds to $900$
• $486$ rounds to $500$

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

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