Can you give me some hints on solving following summation. Is there any theory concerning the following summation?
$p$ is a prime number > 2
$$sum_{s=2}^{p-1}left(leftlfloorfrac{p}{s}rightrfloor sright)$$
I tried to apply the following formula
$$leftlfloor frac{x}{y}rightrfloor = frac{x - (xmod{y})}{y}.$$
But it does not get me anything useful.
Thanks in Advance.
