Total number of peercoins

The total number of peercoins must be: M = (PQ) / V

Wut?

I believe he means this:

M is the total nominal amount of money supply in circulation on average in an economy. V is the velocity of money, that is the average frequency with which a unit of money is spent. P is the price level. Q is an index of real expenditures (on newly produced goods and services).
