The question makes no sense.. you can easily find the sum of integers between 1 and 300 but what does 11 or 13 have to do with it.
The sum of the integers from 1 to 100 inclusive is 5,050.
55 Basically the sum of al integers from 1 to n is Sn=(n²+n)/2 (Think why is this number always an integer!)
-10
The sum of integers from 1 to 2008 = 2008*2009/2 = 2017063
No. The sum of all integers between 1 and 500 is 124,749.
55
The sum of all the the integers between 1 and 2008 (2 through 2,007) is 2,017,036.

Assuming the question refers to INTEGERS and not numbers, the answer is 55.
Yes. The sum of 1 to 10 (inclusive) is 55.
The sum of the first 10 positive integers 1,2,3,4,5,6,7,8,9 and 10 is 55. The sum of the first 10 negative integers -1,-2,-3,-4,-5,-6,-7,-8,-9 and -10 is -55. The sum of the first 10 positive plus the sum of the first 10 negative integers is 0
There are 5390 such integers.
Between 1 and 3000, ie the sum of 2, 3, , ... , 2999 is 4498499
The sum of the integers from 1 to 100 inclusive is 5,050.
If you write down all of the integers between the two numbers, your sum is equivalent to 5,659.
The sum of the first 10 positive integers, using the formula N1 + (N1 + 1) + ... + N2 = N2 * (N2 + 1) / 2 - (N1 - 1) * N1 / 2 is: 55
