I would use 40 for the 38 and 50 for the 51.
90 would be my estimate.
If I had to, I would use 20 and 70.

To find the sum of all odd numbers from 1 to 499, we can use the formula for the sum of an arithmetic series. The formula is n/2 * (first term + last term), where n is the number of terms. In this case, there are 250 odd numbers from 1 to 499. So, the sum would be 250/2 * (1 + 499) = 125 * 500 = 62,500.
416, is 832 divided by two, so, adding 416 and 416 together would give it to you, or if you can't use the same numbers, 417 and 415 would work.

17 and 4: sum is 21.
you can use whole numbers
You could use 250 and 750.
If I had to, I would use 20 and 70.
Well, honey, if you wanna estimate the sum of 17 and 75, you could round them both to the nearest ten. So, 17 rounds up to 20 and 75 rounds down to 70. Add those together and you get a rough estimate of 90. But hey, who needs estimates when you can just do the math and get the exact sum of 92?
To find the sum of 8 numbers when the mean is 23, you can use the formula: sum = mean × number of values. In this case, the sum would be 23 × 8, which equals 184. Therefore, the sum of the 8 numbers is 184.
When working with very large numbers or very small numbers and they would use a system of numeracy known as scientific notation.
use the numbers 5,6,7,8 to write an equation with the largest possible equation

Benchmarks can be used to estimate sums by rounding the numbers to the nearest easy-to-work-with values, such as whole numbers or multiples of ten. This simplifies the addition process and allows for a quick mental calculation. For example, if estimating the sum of 47 and 36, rounding 47 to 50 and 36 to 40 makes it easier to quickly estimate the sum as 90. This method provides a close approximation, helping to assess the reasonableness of the actual sum.

To automatically add a set of numbers together, you use the plus sign (+). In programming or spreadsheet applications, functions like SUM can also be employed to sum a range of numbers. For example, in Excel, you would use =SUM(A1:A10) to total the values from cells A1 to A10.
