Here, we will not only tell you what the sum of integers from 1 to 8015 is, but also show you how to calculate it fast. The sum of the integers from 1 to 8015 is 32,124,120.
To get the answer above, you could add up all the digits like 1+2+3... +8015, 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=8015, thus you get your answer by entering 8015 in the formula like this:
8015(8015 + 1)/2 = 32,124,120
