Here, we will not only tell you what the sum of integers from 1 to 3249 is, but also show you how to calculate it fast. The sum of the integers from 1 to 3249 is 5,279,625.
To get the answer above, you could add up all the digits like 1+2+3... +3249, 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=3249, thus you get your answer by entering 3249 in the formula like this:
3249(3249 + 1)/2 = 5,279,625
