Oh, dude, estimating a range for each sum is like figuring out how much Pizza you'll eat at a party - you just gotta eyeball it. You take the numbers, round 'em to the nearest 10 or 100, depending on how lazy you're feeling, and then add 'em up. If you're feeling fancy, you can even throw in a little wiggle room for error, but who has time for that? Just trust your gut and hope for the best!
To estimate a range for each sum, you can use rounding. Round each number to the nearest place value you are interested in (e.g., nearest ten, hundred, etc.) and then add or subtract the rounded numbers to get the estimated range. For example, if you are adding 345 and 217, you could round 345 to 350 and 217 to 220, then add 350 and 220 to get 570 as the upper end of the range. Subtracting 5 from 350 and 20 from 220 gives you 330 as the lower end of the range.
Well, when estimating a range for each sum, you can start by looking at the numbers you're adding together. Round each number to the nearest ten or hundred, depending on the level of precision you need. Then, add the rounded numbers together to get an estimated range for the sum. Remember, it's all about making an educated guess and finding a balance between accuracy and simplicity. Just trust your instincts and let your creativity guide you!
First, round the highest place value of each number: 400+200+700=1300 Second, round the second highest place value of each number: 390+190+740=1320 The range to estimate the sum is 1300 to 1320. The actual sum is 1321, which higher than the range. However, the actual sum may lie within the obtained range. LEF

The data wasn't provided to answer this question. The range in math is the highest number minus the lowest number. For example 30,20,10,5 the range would be 30 minus 5 which equals 25.

That equals 16.7 which would be between 15 and 18.
The range of a single number - with or without a decimal - is zero.
Round down and round up. The answer will be between 20 (7 + 13) and 22 (8 + 14)
