esimate each sum or difference by rounding to the place value indicated.
37,097 - 20,364 ten thousand
37 thousand plus 20 thousand = ?
round each to the place indicated
To estimate the sum or difference by rounding, you need to round each number to the indicated place value. In this case, we want to estimate the difference, so we'll round both numbers to the nearest ten thousand.
To round 37,097 to the nearest ten thousand, look at the digit in the ten-thousand place. The digit directly to the right of it is 9, which is greater than or equal to 5. Therefore, you'll round up the ten thousand digit, which means the rounded value is 40,000.
Next, round 20,364 to the nearest ten thousand. Again, look at the digit in the ten-thousand place. The digit directly to the right of it is 3, which is less than 5. Therefore, you'll round down the ten thousand digit, which means the rounded value is 20,000.
Finally, subtract the rounded numbers: 40,000 - 20,000 = 20,000.
Therefore, by rounding to the nearest ten thousand, the estimated difference of 37,097 - 20,364 is 20,000.
