Here, we will not only tell you what the sum of integers from 1 to 675 is, but also show you how to calculate it fast. The sum of the integers from 1 to 675 is 228,150.
To get the answer above, you could add up all the digits like 1+2+3... +675, 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=675, thus you get your answer by entering 675 in the formula like this:
675(675 + 1)/2 = 228,150
