Question

Sum of all integers from -100 to 100

Answer 1

Answer:

The sum of all integers from -100 to 100 is 0

Step-by-step explanation:

To get the answer above, you could add up all the digits like 1+2+3... +100, 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=100, thus you get your answer by entering 100 in the formula like this:

100(100 + 1)/2 = 5,050

The sum of integers between (-100) to 0.

(-5050)

Add them = 0
