Here, we will not only tell you what the sum of integers from 1 to 1530 is, but also show you how to calculate it fast. The sum of the integers from 1 to 1530 is 1,171,215.
To get the answer above, you could add up all the digits like 1+2+3... +1530, 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=1530, thus you get your answer by entering 1530 in the formula like this:
1530(1530 + 1)/2 = 1,171,215
