Here, we will not only tell you what the sum of integers from 1 to 3653 is, but also show you how to calculate it fast. The sum of the integers from 1 to 3653 is 6,674,031.
To get the answer above, you could add up all the digits like 1+2+3... +3653, 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=3653, thus you get your answer by entering 3653 in the formula like this:
3653(3653 + 1)/2 = 6,674,031
