A well –known that the following simple formula of the sum of first n natural numbers
$\sum_{k=1}^n k=\frac{n(n+1)}{2}\;\;(1)$
was proved by Gauss. In the present talk the formula of the sum of first n natural numbers (1) with
many proofs is considered. The solutions of several mathematical olympiad problems involving
sums are presented.
