The sum is 1511.
The options are infinite: Ex: 250 + 250 1 + 499 2 + 498 3 + 497 4 + 496 5 + 495 etc...
497 + 498 + 499 + 500 = 1994 (-496) + (-495) +...+ (-1) + 0 + 1+ ... + 500 = 1994 (-1993) + (-1992) + ... + (-1) + 0 + 1 + ... 1994 = 1994
The sum of the first 500 positive integers is: 1 + 2 + 3 + ... + 498 + 499 + 500 = 125250
To find the sum of a set of numbers, you can use this formula: ∑ = (x)(x+1)/2 That is..... The sum = (The number of samples)(The number of samples + 1)/2 Example: What is the sum of all numbers between 500 and 1000? Assuming that we do not include 500 or 1000 in our answer, we have 498 numbers to add up. Let's put that into the formula.... ∑ = (498)(498+1)/2 ∑ = (498)(499)/2 ∑ = (248,502)/2 ∑ = 124,251 The Answer is 124,251
The sum of 30,000,000 and 500 is 30,000,500

The sum is 1300
To find the mean, you need to add all the values and divide by the number of values. Looking closely at the data, you'll notice that the first number is the negative of the last, the second number is the negative of the last but one and so on. This means that the sum of the pairs of numbers at the same position from each end is 0, and so the sum of all the numbers is 0. If the sum is zero, then dividing this by any number greater than zero will lead to zero. The number of elements in the dataset is greater than zero. Thus the mean of the dataset {-500, -499, -498, ..., -1, 0, 1, ..., 498, 499, 500} is 0. If you want to know how many elements there were, then there are 500 - -500 + 1 = 1001 elements in the data set.
500 + 4 = 504

The difference between 400 and the sum of 821 and 77 can be calculated by first finding the sum of 821 and 77, which is 898. Then, subtract 898 from 400 to find the difference. Mathematically, this can be represented as 400 - (821 + 77) = 400 - 898 = -498. Therefore, the difference between 400 and the sum of 821 and 77 is -498.
500 + 400 = 900
