## What is 1 100 added together?

What is the sum of the first 100 whole numbers? Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101. Gauss realized then that his final total would be 50(101) = 5050.

## What is Gauss formula?

Gauss’s method forms a general formula for the sum of the first n integers, namely that 1+2+3+\ldots +n=\frac{1}{2}n(n+1) One way of presenting Gauss‘ method is to write out the sum twice, the second time reversing it as shown. If we add both rows we get the sum of 1 to n, but twice.
