Denzin Theorem

The Denzin Theorem is a mathematical theorem that I devised when trying to answer a math question. At first I wrote a wikipedia article outlining the main points and origins of the theorem, but it was promptly deleted to my great sorrow. The theorem is as follows:

x/(y*10^-z)=x/(y*(1/10^z))=(x/y)*(1/(1/10^z))=(x/y)*10^z or (x*10^z)/y

This theorem was created after much debate and confusion over a simple problem(one that was solved before the theorem was even created). Even after it was forged the theorem proved useless, because due to miscommunication the problem at hand wasn't the problem the theorem set out to solve.
