Let $n$ be a positive integer. Prove that for any real number $x$, $\left \lfloor nx \right \rfloor \ = \ \sum_{n-1}^{i=0}\left ( \left \lfloor x + \frac{i}{n} \right \rfloor \right )$

Re: Problem of Charles Hermite
Ha Ha, that's the Hermite's Identity.
Hint: Write $x=\lfloor x\rfloor+\{x\}$ where $\lfloor x\rfloor$ is the integer part of $x$ and $\{x\}$ is the fractional one.
If you can't do it, see this
