Here, we will not only tell you what the sum of integers from 1 to 2526 is, but also show you how to calculate it fast. The sum of the integers from 1 to 2526 is 3,191,601.
To get the answer above, you could add up all the digits like 1+2+3... +2526, but there is a much easier way to do it! Use the following formula:
n(n + 1)/2 = Sum of Integers
In this case, n=2526, thus you get your answer by entering 2526 in the formula like this:
2526(2526 + 1)/2 = 3,191,601
