Here, we will not only tell you what the sum of integers from 1 to 3797 is, but also show you how to calculate it fast. The sum of the integers from 1 to 3797 is 7,210,503.
To get the answer above, you could add up all the digits like 1+2+3... +3797, 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=3797, thus you get your answer by entering 3797 in the formula like this:
3797(3797 + 1)/2 = 7,210,503
