Number theory proof
Show that the integer n is even if and only if n - 2[n/2] = 0 Thanks very much.:)
1. Suppose n is even, then it may be written n=2k, for some k in N. Then n-2[n/2]=2k-2[k], but k is in N so [k]=k, therefore n-2[n/2]=2k-2k=0. Which is half of the proof, we have proven that if n is
